Tabs are a set of layered sections of content (known as tab panels) that display
one panel of content at a time. Each tab panel has an associated tab element,
that when activated, displays the panel. The list of tab elements is arranged
along the top edge of the currently displayed panel.

## Example

```jsx live
<Tabs>
  <TabList>
    <Tab>First tab</Tab>
    <Tab>Second tab</Tab>
  </TabList>
  <TabPanels>
    <TabPanel>
      <Stack paddingY="medium">
        <Placeholder label="Content from first panel" height={64} />
      </Stack>
    </TabPanel>
    <TabPanel>
      <Stack paddingY="medium">
        <Placeholder label="Content from second panel" height={64} />
      </Stack>
    </TabPanel>
  </TabPanels>
</Tabs>
```

### Default Index

By default, users will be shown the first tab. This can be overridden by
providing a `defaultIndex` prop. You can also have _no_ tabs active by default
by providing a `defaultIndex` of `-1`.

```jsx live
<Tabs defaultIndex={1}>
  <TabList>
    <Tab>First tab</Tab>
    <Tab>Second tab (default)</Tab>
  </TabList>
  <TabPanels>
    <TabPanel>
      <Stack paddingY="medium">
        <Placeholder label="Content from first panel" height={64} />
      </Stack>
    </TabPanel>
    <TabPanel>
      <Stack paddingY="medium">
        <Placeholder
          label="Content from second panel (this should be selected by default)"
          height={64}
        />
      </Stack>
    </TabPanel>
  </TabPanels>
</Tabs>
```

### Disabled tabs

Individual tabs can be be disabled by providing them with a `disabled` prop.

```jsx live
<Tabs>
  <TabList>
    <Tab>First tab</Tab>
    <Tab>Second tab</Tab>
    <Tab disabled>Third tab (disabled)</Tab>
  </TabList>
  <TabPanels>
    <TabPanel>
      <Stack paddingY="medium">
        <Placeholder label="Content from first panel" height={64} />
      </Stack>
    </TabPanel>
    <TabPanel>
      <Stack paddingY="medium">
        <Placeholder label="Content from second panel" height={64} />
      </Stack>
    </TabPanel>
    <TabPanel>
      <Stack paddingY="medium">
        <Placeholder
          label="Content from third panel. You should not be able to see me!"
          height={64}
        />
      </Stack>
    </TabPanel>
  </TabPanels>
</Tabs>
```

### Manual Activation

By default, when a tab has focus, users can cycle through the enabled tabs using
the arrow keys. If `activationMode` is set to `"manual"`, users can activate a
tab by pressing the `Enter` or `Space` key when the tab you want to view has
focus.

It is very important for usability that functionality of components behaves in a
consistent manor. It is therefore recommended that you _do not_ use the manual
activation mode unless you absolutely need it.

```jsx live
<Tabs activationMode="manual">
  <TabList>
    <Tab>First tab</Tab>
    <Tab>Second tab</Tab>
  </TabList>
  <TabPanels>
    <TabPanel>
      <Stack paddingY="medium">
        <Placeholder label="Content from first panel" height={64} />
      </Stack>
    </TabPanel>
    <TabPanel>
      <Stack paddingY="medium">
        <Placeholder label="Content from second panel" height={64} />
      </Stack>
    </TabPanel>
  </TabPanels>
</Tabs>
```
