Features#


Breadcrumbs provide a list of links to parent pages of the current page in hierarchical order. Breadcrumbs helps implement these in an accessible way.

  • Flexible – Support for HTML navigation links, JavaScript handled links, and client side routing.
  • Accessible – Implemented as an ordered list of links. The last link is automatically marked as the current page using aria-current.
  • Styleable – Hover, press, and keyboard focus states are provided for easy styling. These states only apply when interacting with an appropriate input device, unlike CSS pseudo classes.

Anatomy#


TrendSub ItemJanuary 2019 AssetsBreadcrumb itemSeparatorCurrent pageNavigation

Breadcrumbs consist of a list of links, typically with a visual separator icon between each item. The last link represents the current page in the hierarchy, with the previous links representing the parent pages of the current page. Each of these parent links can be clicked, tapped, or triggered via the Enter key to navigate to that page.

Concepts#

Breadcrumbs makes use of the following concepts:

Collections
Defining collections of items, async loading, and updating items over time.

Composed components#

Breadcrumbs uses the following components, which may also be used standalone or reused in other components.

Link
A link allows a user to navigate to another page.

Starter kits#


To help kick-start your project, we offer starter kits that include example implementations of all React Aria components with various styling solutions. All components are fully styled, including support for dark mode, high contrast mode, and all UI states. Each starter comes with a pre-configured Storybook that you can experiment with, or use as a starting point for your own component library.

Content#


Breadcrumbs follows the Collection Components API, accepting both static and dynamic collections. The examples above show static collections, which can be used when the full list of options is known ahead of time. Dynamic collections, as shown below, can be used when the options come from an external data source such as an API call, or update over time.

As seen below, an iterable list of options is passed to the Breadcrumbs using the items prop. A function provided as children of the <Breadcrumbs> is called to render each item. When a breadcrumb is pressed, the onAction event is triggered and the breadcrumbs array is updated.

import type {Key} from 'react-aria-components';

function Example() {
  let [breadcrumbs, setBreadcrumbs] = React.useState([
    {id: 1, label: 'Home'},
    {id: 2, label: 'Trendy'},
    {id: 3, label: 'March 2022 Assets'}
  ]);

  let navigate = (id: Key) => {
    let i = breadcrumbs.findIndex(item => item.id === id);
    setBreadcrumbs(breadcrumbs.slice(0, i + 1));
  };

  return (
    <Breadcrumbs items={breadcrumbs} onAction={navigate}>
      {item => <Breadcrumb><Link>{item.label}</Link></Breadcrumb>}
    </Breadcrumbs>
  );
}
import type {Key} from 'react-aria-components';

function Example() {
  let [breadcrumbs, setBreadcrumbs] = React.useState([
    { id: 1, label: 'Home' },
    { id: 2, label: 'Trendy' },
    { id: 3, label: 'March 2022 Assets' }
  ]);

  let navigate = (id: Key) => {
    let i = breadcrumbs.findIndex((item) => item.id === id);
    setBreadcrumbs(breadcrumbs.slice(0, i + 1));
  };

  return (
    <Breadcrumbs items={breadcrumbs} onAction={navigate}>
      {(item) => (
        <Breadcrumb>
          <Link>{item.label}</Link>
        </Breadcrumb>
      )}
    </Breadcrumbs>
  );
}
import type {Key} from 'react-aria-components';

function Example() {
  let [
    breadcrumbs,
    setBreadcrumbs
  ] = React.useState([
    {
      id: 1,
      label: 'Home'
    },
    {
      id: 2,
      label: 'Trendy'
    },
    {
      id: 3,
      label:
        'March 2022 Assets'
    }
  ]);

  let navigate = (
    id: Key
  ) => {
    let i = breadcrumbs
      .findIndex(
        (item) =>
          item.id === id
      );
    setBreadcrumbs(
      breadcrumbs.slice(
        0,
        i + 1
      )
    );
  };

  return (
    <Breadcrumbs
      items={breadcrumbs}
      onAction={navigate}
    >
      {(item) => (
        <Breadcrumb>
          <Link>
            {item.label}
          </Link>
        </Breadcrumb>
      )}
    </Breadcrumbs>
  );
}

Client side routing#

The <Link> component works with frameworks and client side routers like Next.js and React Router. As with other React Aria components that support links, this works via the RouterProvider component at the root of your app. See the client side routing guide to learn how to set this up.

Separator icons#


The above examples use the CSS :after pseudo class to add separators between each item. These may also be DOM elements instead, e.g. SVG icons. Be sure that they have aria-hidden="true" so they are hidden from assistive technologies.

import ChevronIcon from '@spectrum-icons/workflow/ChevronDoubleRight';

<Breadcrumbs>
  <Breadcrumb className="my-item">
    <Link href="/">Home</Link>
    <ChevronIcon size="S" />
  </Breadcrumb>
  <Breadcrumb><Link>React Aria</Link></Breadcrumb>
</Breadcrumbs>
import ChevronIcon from '@spectrum-icons/workflow/ChevronDoubleRight';

<Breadcrumbs>
  <Breadcrumb className="my-item">
    <Link href="/">Home</Link>
    <ChevronIcon size="S" />
  </Breadcrumb>
  <Breadcrumb>
    <Link>React Aria</Link>
  </Breadcrumb>
</Breadcrumbs>
import ChevronIcon from '@spectrum-icons/workflow/ChevronDoubleRight';

<Breadcrumbs>
  <Breadcrumb className="my-item">
    <Link href="/">
      Home
    </Link>
    <ChevronIcon size="S" />
  </Breadcrumb>
  <Breadcrumb>
    <Link>
      React Aria
    </Link>
  </Breadcrumb>
</Breadcrumbs>
Show CSS
.my-item svg {
  vertical-align: middle;
  padding: 0 5px;
  margin-top: -2px;
}
.my-item svg {
  vertical-align: middle;
  padding: 0 5px;
  margin-top: -2px;
}
.my-item svg {
  vertical-align: middle;
  padding: 0 5px;
  margin-top: -2px;
}

Landmarks#


When breadcrumbs are used as a main navigation element for a page, they can be placed in a navigation landmark. Landmarks help assistive technology users quickly find major sections of a page. Place breadcrumbs inside a <nav> element with an aria-label to create a navigation landmark.

<nav aria-label="Breadcrumbs">
  <Breadcrumbs>
    <Breadcrumb><Link href="/">Home</Link></Breadcrumb>
    <Breadcrumb><Link href="/react-aria/">React Aria</Link></Breadcrumb>
    <Breadcrumb><Link>Breadcrumbs</Link></Breadcrumb>
  </Breadcrumbs>
</nav>
<nav aria-label="Breadcrumbs">
  <Breadcrumbs>
    <Breadcrumb>
      <Link href="/">Home</Link>
    </Breadcrumb>
    <Breadcrumb>
      <Link href="/react-aria/">React Aria</Link>
    </Breadcrumb>
    <Breadcrumb>
      <Link>Breadcrumbs</Link>
    </Breadcrumb>
  </Breadcrumbs>
</nav>
<nav aria-label="Breadcrumbs">
  <Breadcrumbs>
    <Breadcrumb>
      <Link href="/">
        Home
      </Link>
    </Breadcrumb>
    <Breadcrumb>
      <Link href="/react-aria/">
        React Aria
      </Link>
    </Breadcrumb>
    <Breadcrumb>
      <Link>
        Breadcrumbs
      </Link>
    </Breadcrumb>
  </Breadcrumbs>
</nav>

It is best to keep the number of landmarks on a page to a minimum, so only place breadcrumbs in a navigation landmark when it represents the primary or secondary navigation for the page. For example, breadcrumbs within table rows or popovers most likely should not be landmarks.

Disabled#


Breadcrumbs can be disabled using the isDisabled prop. This indicates that navigation is not currently available. When a breadcrumb is disabled, onPress will not be triggered, navigation will not occur, and links will be marked as aria-disabled for assistive technologies.

<Breadcrumbs isDisabled>
  <Breadcrumb><Link href="/">Home</Link></Breadcrumb>
  <Breadcrumb><Link href="/react-aria/">React Aria</Link></Breadcrumb>
  <Breadcrumb><Link>Breadcrumbs</Link></Breadcrumb>
</Breadcrumbs>

    </Link>
  </Breadcrumb>
</Breadcrumbs>
Show CSS
.react-aria-Breadcrumbs {
  .react-aria-Link {
    &[data-disabled] {
      cursor: default;

      &:not([data-current]) {
        color: var(--text-color-disabled);
      }
    }
  }
}
.react-aria-Breadcrumbs {
  .react-aria-Link {
    &[data-disabled] {
      cursor: default;

      &:not([data-current]) {
        color: var(--text-color-disabled);
      }
    }
  }
}
.react-aria-Breadcrumbs {
  .react-aria-Link {
    &[data-disabled] {
      cursor: default;

      &:not([data-current]) {
        color: var(--text-color-disabled);
      }
    }
  }
}

Individual breadcrumbs can also be disabled by passing the isDisabled prop to the <Link> element:

<Breadcrumbs>
  <Breadcrumb>
    <Link href="/">Home</Link>
  </Breadcrumb>
  <Breadcrumb>
    <Link isDisabled href="/react-aria/">React Aria</Link>

Styling#


React Aria components can be styled in many ways, including using CSS classes, inline styles, utility classes (e.g. Tailwind), CSS-in-JS (e.g. Styled Components), etc. By default, all components include a builtin className attribute which can be targeted using CSS selectors. These follow the react-aria-ComponentName naming convention.

.react-aria-Breadcrumbs {
  /* ... */
}
.react-aria-Breadcrumbs {
  /* ... */
}
.react-aria-Breadcrumbs {
  /* ... */
}

A custom className can also be specified on any component. This overrides the default className provided by React Aria with your own.

<Breadcrumbs className="my-breadcrumbs">
  {/* ... */}
</Breadcrumbs>
<Breadcrumbs className="my-breadcrumbs">
  {/* ... */}
</Breadcrumbs>
<Breadcrumbs className="my-breadcrumbs">
  {/* ... */}
</Breadcrumbs>

In addition, some components support multiple UI states (e.g. focused, placeholder, readonly, etc.). React Aria components expose states using data attributes, which you can target in CSS selectors. For example:

.react-aria-Link[data-current] {
  /* ... */
}
.react-aria-Link[data-current] {
  /* ... */
}
.react-aria-Link[data-current] {
  /* ... */
}

The className and style props also accept functions which receive states for styling. This lets you dynamically determine the classes or styles to apply, which is useful when using utility CSS libraries like Tailwind.

<Link
  className={({ isCurrent }) => isCurrent ? 'bg-gray-700' : 'bg-gray-600'}
/>
<Link
  className={({ isCurrent }) =>
    isCurrent ? 'bg-gray-700' : 'bg-gray-600'}
/>
<Link
  className={(
    { isCurrent }
  ) =>
    isCurrent
      ? 'bg-gray-700'
      : 'bg-gray-600'}
/>

The states, selectors, and render props for all components used in Breadcrumbs are documented below.

Breadcrumbs can be targed with the .react-aria-Breadcrumbs CSS selector, or by overriding with a custom className. It is rendered as an <ol> element representing the list of items.

A Breadcrumb can be targeted with the .react-aria-Breadcrumb CSS selector, or by overriding with a custom className. It is rendered as an <li> element, and should contain a <Link>. It may also include another element such as a separator icon.

A Link can be targeted with the .react-aria-Link CSS selector, or by overriding with a custom className. It is rendered as an <a> element when a href is provided via props. If only text is provided, it is rendered as a <span>. Links support the following states and render props:

NameCSS SelectorDescription
isCurrent[data-current]Whether the link is the current item within a list.
isHovered[data-hovered]Whether the link is currently hovered with a mouse.
isPressed[data-pressed]Whether the link is currently in a pressed state.
isFocused[data-focused]Whether the link is focused, either via a mouse or keyboard.
isFocusVisible[data-focus-visible]Whether the link is keyboard focused.
isDisabled[data-disabled]Whether the link is disabled.

Advanced customization#


Contexts#

All React Aria Components export a corresponding context that can be used to send props to them from a parent element. This enables you to build your own compositional APIs similar to those found in React Aria Components itself. You can send any prop or ref via context that you could pass to the corresponding component. The local props and ref on the component are merged with the ones passed via context, with the local props taking precedence (following the rules documented in mergeProps).

This example shows a Router component that accepts Breadcrumbs and Link elements as children, and tracks a history stack. When a link is clicked, it is pushed to the stack and automatically updates the breadcrumbs. When a breadcrumb is clicked, the stack is popped to that location.

import type {PressEvent} from 'react-aria-components';
import {BreadcrumbsContext, LinkContext} from 'react-aria-components';

interface RouterItem {
  id: number,
  label: string
}

function Router({children}) {
  let [items, setItems] = React.useState<RouterItem[]>([
    {id: 0, label: 'Home'},
    {id: 1, label: 'React Aria'},
  ]);

  // Pop stack when a breadcrumb item is clicked.
  let onAction = (id: Key) => {
    let i = items.findIndex(item => item.id === id);
    setItems(items.slice(0, i + 1));
  };

  // Push stack when a link is clicked.
  let onPress = (e: PressEvent) => {
    let label = e.target.textContent;
    setItems(items.concat({id: items.length, label}));
  };

  return (
    <BreadcrumbsContext.Provider value={{items, onAction}}>      <LinkContext.Provider value={{onPress}}>
        {children}
      </LinkContext.Provider>
    </BreadcrumbsContext.Provider>
  );
}
import type {PressEvent} from 'react-aria-components';
import {
  BreadcrumbsContext,
  LinkContext
} from 'react-aria-components';

interface RouterItem {
  id: number;
  label: string;
}

function Router({ children }) {
  let [items, setItems] = React.useState<RouterItem[]>([
    { id: 0, label: 'Home' },
    { id: 1, label: 'React Aria' }
  ]);

  // Pop stack when a breadcrumb item is clicked.
  let onAction = (id: Key) => {
    let i = items.findIndex((item) => item.id === id);
    setItems(items.slice(0, i + 1));
  };

  // Push stack when a link is clicked.
  let onPress = (e: PressEvent) => {
    let label = e.target.textContent;
    setItems(items.concat({ id: items.length, label }));
  };

  return (
    <BreadcrumbsContext.Provider
      value={{ items, onAction }}
    >      <LinkContext.Provider value={{ onPress }}>
        {children}
      </LinkContext.Provider>
    </BreadcrumbsContext.Provider>
  );
}
import type {PressEvent} from 'react-aria-components';
import {
  BreadcrumbsContext,
  LinkContext
} from 'react-aria-components';

interface RouterItem {
  id: number;
  label: string;
}

function Router(
  { children }
) {
  let [items, setItems] =
    React.useState<
      RouterItem[]
    >([
      {
        id: 0,
        label: 'Home'
      },
      {
        id: 1,
        label:
          'React Aria'
      }
    ]);

  // Pop stack when a breadcrumb item is clicked.
  let onAction = (
    id: Key
  ) => {
    let i = items
      .findIndex(
        (item) =>
          item.id === id
      );
    setItems(
      items.slice(
        0,
        i + 1
      )
    );
  };

  // Push stack when a link is clicked.
  let onPress = (
    e: PressEvent
  ) => {
    let label =
      e.target
        .textContent;
    setItems(
      items.concat({
        id: items.length,
        label
      })
    );
  };

  return (
    <BreadcrumbsContext.Provider
      value={{
        items,
        onAction
      }}
    >      <LinkContext.Provider
        value={{
          onPress
        }}
      >
        {children}
      </LinkContext.Provider>
    </BreadcrumbsContext.Provider>
  );
}

Note: LinkContext only affects links outside Breadcrumbs because Breadcrumbs also provides a value for LinkContext which overrides an outer provider. See custom children below for more details.

Now when you place Breadcrumbs inside a Router, it automatically has access to the location history via context.

<Router>
  <Breadcrumbs>
    {(item: RouterItem) => <Breadcrumb><Link>{item.label}</Link></Breadcrumb>}
  </Breadcrumbs>
  <ul>
    <li><Link>Breadcrumbs</Link></li>
    <li><Link>Button</Link></li>
    <li><Link>Calendar</Link></li>
  </ul>
</Router>
<Router>
  <Breadcrumbs>
    {(item: RouterItem) => (
      <Breadcrumb>
        <Link>{item.label}</Link>
      </Breadcrumb>
    )}
  </Breadcrumbs>
  <ul>
    <li>
      <Link>Breadcrumbs</Link>
    </li>
    <li>
      <Link>Button</Link>
    </li>
    <li>
      <Link>Calendar</Link>
    </li>
  </ul>
</Router>
<Router>
  <Breadcrumbs>
    {(
      item: RouterItem
    ) => (
      <Breadcrumb>
        <Link>
          {item.label}
        </Link>
      </Breadcrumb>
    )}
  </Breadcrumbs>
  <ul>
    <li>
      <Link>
        Breadcrumbs
      </Link>
    </li>
    <li>
      <Link>
        Button
      </Link>
    </li>
    <li>
      <Link>
        Calendar
      </Link>
    </li>
  </ul>
</Router>

Custom children#

Breadcrumbs passes props to its child components, such as the links, via their associated contexts. These contexts are exported so you can also consume them in your own custom components. This enables you to reuse existing components from your app or component library together with React Aria Components.

ComponentContextPropsRef
LinkLinkContextLinkPropsHTMLAnchorElement

This example consumes from LinkContext in an existing styled link component to make it compatible with React Aria Components. The useContextProps hook merges the local props and ref with the ones provided via context by Breadcrumbs. useLink returns DOM props to spread onto the link element.

import type {LinkProps} from 'react-aria-components';
import {LinkContext, useContextProps} from 'react-aria-components';

const MyCustomLink = React.forwardRef(
  (props: LinkProps, ref: React.ForwardedRef<HTMLAnchorElement>) => {
    // Merge the local props and ref with the ones provided via context.
    [props, ref] = useContextProps(props, ref, LinkContext);
    // ... your existing Link component
    let { linkProps } = useLink(props, ref);
    return <a {...linkProps} ref={ref} />;
  }
);
import type {LinkProps} from 'react-aria-components';
import {
  LinkContext,
  useContextProps
} from 'react-aria-components';

const MyCustomLink = React.forwardRef(
  (
    props: LinkProps,
    ref: React.ForwardedRef<HTMLAnchorElement>
  ) => {
    // Merge the local props and ref with the ones provided via context.
    [props, ref] = useContextProps(props, ref, LinkContext);
    // ... your existing Link component
    let { linkProps } = useLink(props, ref);
    return <a {...linkProps} ref={ref} />;
  }
);
import type {LinkProps} from 'react-aria-components';
import {
  LinkContext,
  useContextProps
} from 'react-aria-components';

const MyCustomLink =
  React.forwardRef(
    (
      props: LinkProps,
      ref:
        React.ForwardedRef<
          HTMLAnchorElement
        >
    ) => {
      // Merge the local props and ref with the ones provided via context.
      [props, ref] =
        useContextProps(
          props,
          ref,
          LinkContext
        );
      // ... your existing Link component
      let { linkProps } =
        useLink(
          props,
          ref
        );
      return (
        <a
          {...linkProps}
          ref={ref}
        />
      );
    }
  );

Now you can use MyCustomLink within Breadcrumbs, in place of the builtin React Aria Components Link.

<Breadcrumbs>
  <Breadcrumb><MyCustomLink>Custom link</MyCustomLink></Breadcrumb>  {/* ... */}
</Breadcrumbs>
<Breadcrumbs>
  <Breadcrumb>
    <MyCustomLink>Custom link</MyCustomLink>
  </Breadcrumb>  {/* ... */}
</Breadcrumbs>
<Breadcrumbs>
  <Breadcrumb>
    <MyCustomLink>
      Custom link
    </MyCustomLink>
  </Breadcrumb>  {/* ... */}
</Breadcrumbs>
