Breadcrumb
A breadcrumb indicates the location of the user within a navigation's hierarchy.
When to use
Use a breadcrumb in the following cases:
- When the app has more than two navigation levels.
- When there is a large amount of hierarchically structured content.
General construction
A breadcrumb consists of the following elements:
1. Clickable item
- Each item represents a single section in a hierarchical path.
- A clickable item contains a link to its corresponding page in the hierarchy. The text of the item is the same as the title of the destination page.
2. Separator
- It separates the breadcrumb items from each other.
3. Not clickable item (optional)
- A not clickable item is a structural container in the hierarchy which is not reachable by the user.
4. Current page (optional)
- The current page is the last item of the breadcrumb.
- It is a not clickable item.
Behavior
Breadcrumb
The path shows every level from the first page of the application to the current page.
Interaction
- A clickable item contains a link to a page.
- A not clickable item is just a structural level without reachable content.
- The last item of a breadcrumb can indicate the current page. If so it is not clickable and displays the current page’s title.
- A separator is not clickable.
Do’s & Don’ts
- Show a breadcrumb only when hierarchical navigation is possible.
- Do not use a breadcrumb if the navigation’s hierarchy contains only one level.
This chapter shows several breadcrumb styles in the design system.
