Breadcrumbs visually depict the structural hierarchy of a digital product. They guide users through layers of content, showing where they are within the system. Each breadcrumb link corresponds to a specific level in the hierarchy. They typically appear horizontally at the top of a digital product.

When not to use

Limited content depth

When your digital product has shallow navigation, breadcrumbs may add clutter without significant benefit. If there are only one or two layers of hierarchy, users can find their way without breadcrumbs.

The actual path a user takes during their session may differ from the breadcrumb trail and is not shown within the breadcrumb. Users might jump directly from one section to another, use search functionality, or follow external links. Their journey can be nonlinear and influenced by various factors.

Accessibility Considerations

Breadcrumbs are organized using a numbered list. This is because when we label nav elements as 'breadcrumb,' it tells users that this structure is a breadcrumb trail, making it easy for them to find their way around.
We use CSS to add visual separators between breadcrumb items while keeping them hidden from screen readers using aria-hidden. This helps maintain a smooth reading experience.
The separators between breadcrumb items are non-clickable, meaning users won't accidentally interact with them.

Keyboard interactions

Command	Description
Tab	When focus moves away from the breadcrumbs, it automatically shifts to the first breadcrumb item. Similarly, if focus is on a breadcrumb item, it then moves to the next breadcrumb item in the sequence.
Shift + Tab	Moves focus to previous breadcrumb item.
Enter	Selects the breadcrumb item if it hasn't been already activated.

WAI-ARIA

Attribute	Value	Description	User suppliedSpecifies whether the attribute is always set in the component (no) or it needs to be provided by the developer (yes)
`role`	`'navigation'`	Declare our group of links as navigation, used for navigating through the website/page.	no
`aria-label`	string	Provides a label describing the type of navigation. Added as well to the `sl-button`, which is shown when there are some navigation links collapsed.	no
`aria-hidden`	`true`	Hides the separators between breadcrumb items so they are not announced by a screen reader or any other assistive technology.	no
`aria-current`	`page`	Applied to the last link in the set to indicate that it represents the current page. Used to inform the assistive technology user what has been indicated via styling.	no
`aria-details`	string	In collapsed version: Used to link the popover element (container with more links) with the `sl-button` which is an anchor (element that triggers the popover). It contains `id` of the popover element and is added to the `sl-button` (anchor) element.	no
`aria-expanded`	boolean	In collapsed version: set to `true` (on the `sl-button` anchor element) if the popover (container with more links) is visible, `false` if the popover is hidden.	no
