Tabs

Tabs make it easy to explore and switch between different views.

Tabs organize and allow navigation between groups of content that are related and at the same level of hierarchy.

Basic tabs

Tabs are implemented using a handful of components, each with a specific purpose:

  • TabUnstyled - an actual tab. Clicking on it displays the associated content.
  • TabsListUnstyled - container for tabs. Responsible for handling focus and keyboard navigation between tabs.
  • TabPanelUnstyled - hosts the content associated with a tab.
  • TabsUnstyled - top-level component wrapping TabsListUnstyled and TabPanelUnstyled and letting them communicate.
import TabsUnstyled from '@mui/base/TabsUnstyled';
import TabsListUnstyled from '@mui/base/TabUnstyled';
import TabUnstyled from '@mui/base/TabUnstyled';
import TabPanelUnstyled from '@mui/base/TabPanelUnstyled';

You can associate a tab with tab panel using the value prop. If a tab with a given value is selected, a tab panel with a matching value will be shown.

Note that setting a value on a TabUnstyled is not mandatory. If you omit this prop, it will default to order of a tab within its parent TabsListUnstyled. This order is 0-based (the first tab has its value set to 0, the next one 1, etc.).

First page
<TabsUnstyled defaultValue={0}>
  <TabsListUnstyled>
    <TabUnstyled>One</TabUnstyled>
    <TabUnstyled>Two</TabUnstyled>
    <TabUnstyled>Three</TabUnstyled>
  </TabsListUnstyled>
  <TabPanelUnstyled value={0}>First page</TabPanelUnstyled>
  <TabPanelUnstyled value={1}>Second page</TabPanelUnstyled>
  <TabPanelUnstyled value={2}>Third page</TabPanelUnstyled>
</TabsUnstyled>

Customizing the root element

By default, the TabUnstyled renders a native button element. You are free to override this by setting the component or components.Root prop. If a non-interactive element (such as a span) is provided this way, the TabUnstyled will take care of adding accessibility attributes.

The TabPanelUnstyled, on the other hand, renders a native div element by default. You are free to override this as well by setting the component or components.Root prop on the TabPanelUnstyled.

First page
<TabsUnstyled defaultValue={0}>
  <TabsList>
    <Tab>One</Tab>
    <Tab>Two</Tab>
    <Tab>Three</Tab>
  </TabsList>
  <TabPanel value={0}>First page</TabPanel>
  <TabPanel value={1}>Second page</TabPanel>
  <TabPanel value={2}>Third page</TabPanel>
</TabsUnstyled>

Third-party routing library

One frequent use case is to perform navigation on the client only, without an HTTP round-trip to the server. The Tab component provides the component prop to handle this use case. Here is a more detailed guide.

Accessibility

(WAI-ARIA: https://www.w3.org/TR/wai-aria-practices/#tabpanel)

The following steps are needed in order to provide necessary information for assistive technologies:

  1. Label TabsUnstyled via aria-label or aria-labelledby.
  2. TabUnstyleds need to be connected to their corresponding tab panels by setting the correct id, aria-controls and aria-labelledby.

An example for the current implementation can be found in the demos on this page.

Keyboard navigation

The components implement keyboard navigation using the "manual activation" behavior. If you want to switch to the "selection automatically follows focus" behavior you have pass selectionFollowsFocus to the Tabs component. The WAI-ARIA authoring practices have a detailed guide on how to decide when to make selection automatically follow focus.

Demo

The following two demos only differ in their keyboard navigation behavior. Focus a tab and navigate with arrow keys to notice the difference, e.g. Arrow Right.

/* Tabs where selection follows focus */
<TabsUnstyled selectionFollowsFocus />

Selection following focus:

Selection independent of focus (default behavior):
