Tabs
An accessible tabs component.
The Tab and TabPanel elements are associated by their order in the tree.
None of the components are empty wrappers, each is associated with a real DOM
element in the document, giving you maximum control over styling and
composition.
Import#
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 tabs at the top, at the bottom, or both.

enclosed-colored, soft-rounded, solid-rounded, unstyled

You can also change the color for any specific variant by passing the
variantColor.
The value of variantColor must exist in the theme object, and must be a key
in theme.colors that has the 100 - 900 color values.

Styling the tab states manually#
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 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.
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.
Make a Tab disabled#
When a Tab is disabled, it's skipped during keyboard navigation and it's not
clickable.
Manually Activated Tabs#
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 notable 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.

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.
Click the tabs or pull the slider around
Yeah yeah. What's up?
Oh, hello there.
Creating custom tab components#
Because TabList needs to know the order of the children, we use cloneElement
to pass state internally. If you want to know if a tab is active, you can wrap
it, and then inspect clone props passed in.
Data Tabs#
If you'd like to drive your tabs with an array instead of using the granular components, you can create your own DataTabs component.
