@reach/tabs

Tabs - TabList - Tab - TabPanels - TabPanel

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.

You can render any other elements you want inside of Tabs, but TabList should only render Tab elements, and TabPanels should only render TabPanel elements.

one!

Check out the demos for ideas on how to style and compose.

const TabPage = () => (
  <Tabs>

      <RedTab>This is red</RedTab>

Tab isSelected

Type: number - cloned

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. Note that any props that start with _ are not public API, so don't use them :)

Perhaps the greatest dish ever invented.
