The alignment of the tabs
Tabs
An accessible tabs component that provides keyboard interactions and ARIA attributes described in the WAI-ARIA Tabs Design Pattern.
Import#
import { Tabs, TabList, TabPanels, Tab, TabPanel } from '@chakra-ui/react'
- Tabs: Provides context and state for all components
- TabList: Wrapper for the
Tab
components - Tab: element that serves as a label for one of the tab panels and can be activated to display that panel.
- TabPanels: Wrapper for the
TabPanel
components - TabPanel: element that contains the content associated with a tab
Usage#
You can render any element within Tabs
, but TabList
should only have Tab
as children, and TabPanels
should have TabPanel
as children.
Tabs expects TabList
and TabPanels
as children. The order doesn't matter,
you can have TabList
at the top, at the bottom, or both.
<Tabs><TabList><Tab>One</Tab><Tab>Two</Tab><Tab>Three</Tab></TabList><TabPanels><TabPanel><p>one!</p></TabPanel><TabPanel><p>two!</p></TabPanel><TabPanel><p>three!</p></TabPanel></TabPanels></Tabs>
Tab variants and color#
Tabs come in 6 different variants to style the tabs: line
,enclosed
,
enclosed-colored
, soft-rounded
, solid-rounded
<Tabs variant='enclosed'><TabList><Tab>One</Tab><Tab>Two</Tab></TabList><TabPanels><TabPanel><p>one!</p></TabPanel><TabPanel><p>two!</p></TabPanel></TabPanels></Tabs>
You can also change the color scheme for any specific variant by passing the
colorScheme
.
The value of
colorScheme
must exist in the theme object, and must be a key intheme.colors
that has the50
-900
color values.
<Tabs variant='soft-rounded' colorScheme='green'><TabList><Tab>Tab 1</Tab><Tab>Tab 2</Tab></TabList><TabPanels><TabPanel><p>one!</p></TabPanel><TabPanel><p>two!</p></TabPanel></TabPanels></Tabs>
Tab sizes#
You can change the size of the tab by passing size
prop. We support 3 sizes
sm
, md
, lg
<Tabs size='md' variant='enclosed'><TabList><Tab>One</Tab><Tab>Two</Tab></TabList><TabPanels><TabPanel><p>one!</p></TabPanel><TabPanel><p>two!</p></TabPanel></TabPanels></Tabs>
Changing the tabs alignment#
You can change the alignment of the TabList
by passing align
prop. We
support 3 sizes start
, center
, end
.
<Tabs align='end' variant='enclosed'><TabList><Tab>One</Tab><Tab>Two</Tab></TabList><TabPanels><TabPanel><p>one!</p></TabPanel><TabPanel><p>two!</p></TabPanel></TabPanels></Tabs>
Fitted Tabs#
Stretch the tab list to fit the container by passing isFitted
prop.
<Tabs isFitted variant='enclosed'><TabList mb='1em'><Tab>One</Tab><Tab>Two</Tab></TabList><TabPanels><TabPanel><p>one!</p></TabPanel><TabPanel><p>two!</p></TabPanel></TabPanels></Tabs>
Styling the tab states via props#
In event you need to create custom styles for the tabs. Simply set the variant
to unstyled
, and use the _selected
, _hover
, _active
style props.
<Tabs variant='unstyled'><TabList><Tab _selected={{ color: 'white', bg: 'blue.500' }}>Tab 1</Tab><Tab _selected={{ color: 'white', bg: 'green.400' }}>Tab 2</Tab></TabList><TabPanels><TabPanel><p>one!</p></TabPanel><TabPanel><p>two!</p></TabPanel></TabPanels></Tabs>
Tabs onChange#
The onChange
callback returns the active tab's index whenever the user changes
tabs. If you intend to control the tabs programmatically, use this with the
index
prop.
function Example() {const colors = useColorModeValue(['red.50', 'teal.50', 'blue.50'],['red.900', 'teal.900', 'blue.900'],)const [tabIndex, setTabIndex] = React.useState(0)const bg = colors[tabIndex]return (<Tabs onChange={(index) => setTabIndex(index)} bg={bg}><TabList><Tab>Red</Tab><Tab>Teal</Tab><Tab>Blue</Tab></TabList><TabPanels p='2rem'><TabPanel>The Primary Colors</TabPanel><TabPanel>Are 1, 2, 3</TabPanel><TabPanel>Red, yellow and blue.</TabPanel></TabPanels></Tabs>)}
Make a tab initially active#
If you want a tab to be initially active, simply pass the defaultIndex
prop
and set it to the index of that tab.
<Tabs defaultIndex={1}><TabPanels><TabPanel><ImageboxSize='200px'fit='cover'src='https://resizing.flixster.com/wTgvsiM8vNLhCcCH-6ovV8n5z5U=/300x300/v1.bjsyMDkxMzI5O2o7MTgyMDQ7MTIwMDsxMjAwOzkwMA'/></TabPanel><TabPanel><ImageboxSize='200px'fit='cover'src='https://vignette.wikia.nocookie.net/naruto/images/2/21/Sasuke_Part_1.png/revision/latest?cb=20170716092103'/></TabPanel></TabPanels><TabList><Tab>Naruto</Tab><Tab>Sasuke</Tab></TabList></Tabs>
Make a Tab disabled#
When a Tab
is disabled, it is skipped during keyboard navigation and it is not
clickable.
function Example() {return (<Tabs><TabList><Tab>One</Tab><Tab isDisabled>Two</Tab><Tab>Three</Tab></TabList><TabPanels><TabPanel>1</TabPanel><TabPanel>2</TabPanel><TabPanel>3</TabPanel></TabPanels></Tabs>)}
Tabs with manual activation#
By default, Tabs
are activated automatically. This means when you use the
arrow keys to change tabs, the tab is activated and focused.
The content of a
TabPanel
should ideally be preloaded. However, if switching to a tab panel causes a network request and possibly a page refresh, there might be some noticeable latency and this might affect the experience for keyboard and screen reader users.
In this scenario, you should use a manually activated tab, it moves focus without activating the tabs. With focus on a specific tab, users can activate a tab by pressing Space or Enter.
<Tabs isManual variant='enclosed'><TabList><Tab>One</Tab><Tab>Two</Tab></TabList><TabPanels><TabPanel><p>one!</p></TabPanel><TabPanel><p>two!</p></TabPanel></TabPanels></Tabs>
Lazily mounting tab panels#
By default, the Tabs
component renders all tabs content to the DOM, meaning
that invisible tabs are still rendered but are hidden by styles.
If you want to defer rendering of each tab until that tab is selected, you can
use the isLazy
prop. This is useful if your tabs require heavy performance, or
make network calls on mount that should only happen when the component is
displayed.
<Tabs isLazy><TabList><Tab>One</Tab><Tab>Two</Tab></TabList><TabPanels>{/* initially mounted */}<TabPanel><p>one!</p></TabPanel>{/* initially not mounted */}<TabPanel><p>two!</p></TabPanel></TabPanels></Tabs>
Controlled Tabs#
Like form inputs, a tab's state can be controlled. Make sure to include an onChange as well, or else the tabs will not be interactive.
function ControlledExample() {const [tabIndex, setTabIndex] = React.useState(0)const handleSliderChange = (event) => {setTabIndex(parseInt(event.target.value, 10))}const handleTabsChange = (index) => {setTabIndex(index)}return (<Box><inputtype='range'min='0'max='2'value={tabIndex}onChange={handleSliderChange}/><Tabs index={tabIndex} onChange={handleTabsChange}><TabList><Tab>One</Tab><Tab>Two</Tab><Tab>Three</Tab></TabList><TabPanels><TabPanel><p>Click the tabs or pull the slider around</p></TabPanel><TabPanel><p>Yeah yeah. What's up?</p></TabPanel><TabPanel><p>Oh, hello there.</p></TabPanel></TabPanels></Tabs></Box>)}
Creating custom tab components#
Because TabList
needs to know the order of the children, we use cloneElement
to pass state internally. Your custom Tab
component must use
React.forwardRef
.
function CustomTabs() {// 1. Reuse the styles for the Tabconst StyledTab = chakra('button', { themeKey: 'Tabs.Tab' })const CustomTab = React.forwardRef((props, ref) => {// 2. Reuse the `useTab` hookconst tabProps = useTab({ ...props, ref })const isSelected = !!tabProps['aria-selected']// 3. Hook into the Tabs `size`, `variant`, propsconst styles = useStyles()return (<StyledTab __css={styles.tab} {...tabProps}><Box as='span' mr='2'>{isSelected ? '😎' : '😐'}</Box>{tabProps.children}</StyledTab>)})return (<Tabs><TabList><CustomTab>One</CustomTab><CustomTab>Two</CustomTab></TabList><TabPanels><TabPanel>1</TabPanel><TabPanel>2</TabPanel></TabPanels></Tabs>)}
DataTabs#
If you'd like to drive your tabs with an array instead of using the granular components, you can create your own DataTabs component.
function Example() {// 1. Create the componentfunction DataTabs({ data }) {return (<Tabs><TabList>{data.map((tab, index) => (<Tab key={index}>{tab.label}</Tab>))}</TabList><TabPanels>{data.map((tab, index) => (<TabPanel p={4} key={index}>{tab.content}</TabPanel>))}</TabPanels></Tabs>)}// 2. Create an array of dataconst tabData = [{label: 'Nigerian Jollof',content: 'Perhaps the greatest dish ever invented.',},{label: 'Pounded Yam & Egusi',content:'Perhaps the surest dish ever invented but fills the stomach more than rice.',},]// 3. Pass the props and chill!return <DataTabs data={tabData} />}
Accessibility#
Keyboard#

aria-controls | Set to the id of its associated TabPanel | |
TabList | id | The id of the TabPanel that's referenced by its associated Tab |
aria-orientation | Set to vertical or horizontal based on the value of the orientation prop | |
role="tablist" | Indicates that it is a tablist | |
TabPanel | role="tabpanel" | Indicates that it is a tabpanel |
