# Tabs

Switches between views of the same subject without leaving the page.

```tsx
import { Tabs, TabsContent, TabsList, TabsTrigger } from "@zenoxai/ui/components/tabs"

function TabsDemo() {
  return (
    <Tabs defaultValue="overview" className="w-full max-w-md">
      <TabsList>
        <TabsTrigger value="overview">Overview</TabsTrigger>
        <TabsTrigger value="evidence">Evidence</TabsTrigger>
        <TabsTrigger value="history">History</TabsTrigger>
      </TabsList>
      <TabsContent value="overview" className="text-text-secondary">
        Lookalike domain acme-login.co, first seen 21 October, risk score 87.
      </TabsContent>
      <TabsContent value="evidence" className="text-text-secondary">
        2 screenshots, 1 WHOIS record and the MX records of the domain.
      </TabsContent>
      <TabsContent value="history" className="text-text-secondary">
        Created by domain monitoring. Assigned to the SOC team.
      </TabsContent>
    </Tabs>
  )
}
```

## Usage

```tsx
import {
  Tabs,
  TabsContent,
  TabsList,
  TabsTrigger,
} from "@zenoxai/ui/components/tabs"
```

```tsx
<Tabs defaultValue="overview">
  <TabsList>
    <TabsTrigger value="overview">Overview</TabsTrigger>
    <TabsTrigger value="evidence">Evidence</TabsTrigger>
  </TabsList>
  <TabsContent value="overview">...</TabsContent>
  <TabsContent value="evidence">...</TabsContent>
</Tabs>
```

Use tabs for views of equal weight that the user switches between: the sections of an alert,
the status pivots of a list. Each `TabsTrigger` and its `TabsContent` share a `value`. Keep
labels to one or two words and keep the set to what fits on one line.

The default variant looks like a segmented [Toggle Group](/components/toggle-group): the same
bordered track, and the active tab takes the same selection colors, a primary-soft fill and
text in a primary inset ring, while hover stays neutral. Choose between the two by what they
switch: tabs swap panels, a toggle group changes what one view shows.

Do not use tabs for steps the user must complete in order, or to navigate between pages: use
links. For a short set of options that filter a list in place, use the toggle group.

## Examples

### Line

`variant="line"` on `TabsList` is the tab row under the title of every Zenox module page. The
list spans its container and draws its own bottom rule, and the active tab is marked by primary
text over an underline in the primary color. Put counts in a soft [Badge](/components/badge)
after the label. When the tabs do not fit, on a phone for example, the row scrolls sideways and
keeps its rule; focusing a tab scrolls it into view.

```tsx
import { Badge } from "@zenoxai/ui/components/badge"
import { Tabs, TabsContent, TabsList, TabsTrigger } from "@zenoxai/ui/components/tabs"

function TabsLine() {
  return (
    <Tabs defaultValue="open" className="w-full">
      <TabsList variant="line">
        <TabsTrigger value="open">
          Open
          <Badge variant="soft" tone="neutral">
            24
          </Badge>
        </TabsTrigger>
        <TabsTrigger value="in-progress">
          In progress
          <Badge variant="soft" tone="neutral">
            6
          </Badge>
        </TabsTrigger>
        <TabsTrigger value="resolved">Resolved</TabsTrigger>
        <TabsTrigger value="dismissed">Dismissed</TabsTrigger>
      </TabsList>
      <TabsContent value="open" className="pt-2 text-text-secondary">
        24 alerts are waiting for triage.
      </TabsContent>
      <TabsContent value="in-progress" className="pt-2 text-text-secondary">
        6 alerts are assigned to an analyst.
      </TabsContent>
      <TabsContent value="resolved" className="pt-2 text-text-secondary">
        Alerts closed in the last 90 days.
      </TabsContent>
      <TabsContent value="dismissed" className="pt-2 text-text-secondary">
        Alerts marked as false positives.
      </TabsContent>
    </Tabs>
  )
}
```

### Vertical

Set `orientation="vertical"` on `Tabs` for settings pages with more sections than fit in a
row. The arrow keys follow the orientation: Up and Down move between tabs.

```tsx
import { BellIcon, KeyRoundIcon, UsersIcon } from "lucide-react"
import { Tabs, TabsContent, TabsList, TabsTrigger } from "@zenoxai/ui/components/tabs"

function TabsVertical() {
  return (
    <Tabs
      defaultValue="notifications"
      orientation="vertical"
      className="w-full max-w-md"
    >
      <TabsList>
        <TabsTrigger value="notifications">
          <BellIcon />
          Notifications
        </TabsTrigger>
        <TabsTrigger value="members">
          <UsersIcon />
          Members
        </TabsTrigger>
        <TabsTrigger value="api-keys">
          <KeyRoundIcon />
          API keys
        </TabsTrigger>
      </TabsList>
      <TabsContent value="notifications" className="text-text-secondary">
        Send an email when a critical alert opens.
      </TabsContent>
      <TabsContent value="members" className="text-text-secondary">
        12 members in the Acme Corp tenant.
      </TabsContent>
      <TabsContent value="api-keys" className="text-text-secondary">
        2 active keys. The oldest was created 140 days ago.
      </TabsContent>
    </Tabs>
  )
}
```

## Accessibility

- The list has `role="tablist"`, each trigger `role="tab"` with `aria-selected`, and each
  panel `role="tabpanel"` labelled by its tab. Arrow keys move between tabs, Home and End jump
  to the first and last.
- By default the arrow keys move focus without selecting; Enter or Space selects. Set
  `activateOnFocus` on `TabsList` to select on focus, only when panels render without delay.
- Base UI flips Left and Right in a right-to-left layout. See
  [Direction](/components/direction).

## API reference

`import { ... } from "@zenoxai/ui/components/tabs"`

### Tabs

| Prop | Type | Default | Description |
| --- | --- | --- | --- |
| defaultValue | `any` | `0` | The default value. Use when the component is not controlled. When the value is `null`, no Tab will be active. |
| onValueChange | `((value: any, eventDetails: TabsRootChangeEventDetails) => void)` |  | Callback invoked when new value is being set.  The event `reason` is `'none'` for user-initiated changes, such as a click or keyboard navigation; `'initial'` for the first automatic selection or fallback in uncontrolled roots when `defaultValue` is omitted or `undefined`, including when the implicit initial value is disabled or missing; `'disabled'` for automatic fallback when the selected tab becomes disabled in uncontrolled roots; or `'missing'` for automatic fallback when the selected tab is removed, or when an explicit `defaultValue` never matches a mounted tab in uncontrolled roots.  For automatic changes, the selected value can be `null` when no enabled Tab is available as a fallback.  Automatic changes cannot be canceled; calling `eventDetails.cancel()` for `'initial'`, `'disabled'`, or `'missing'` has no effect. |
| orientation | `"horizontal" \| "vertical"` | `horizontal` | The component orientation (layout flow direction). |
| render | `ReactElement<unknown, string \| JSXElementConstructor<any>> \| ComponentRenderFn<HTMLProps, TabsRootState>` |  | Allows you to replace the component's HTML element with a different tag, or compose it with another component.  Accepts a `ReactElement` or a function that returns the element to render. |
| value | `any` |  | The value of the currently active `Tab`. Use when the component is controlled. When the value is `null`, no Tab will be active. |

### TabsList

| Prop | Type | Default | Description |
| --- | --- | --- | --- |
| activateOnFocus | `boolean` | `false` | Whether to automatically change the active tab on arrow key focus. Otherwise, tabs will be activated using <kbd>Enter</kbd> or <kbd>Space</kbd> key press. |
| loopFocus | `boolean` | `true` | Whether to loop keyboard focus back to the first item when the end of the list is reached while using the arrow keys. |
| render | `ReactElement<unknown, string \| JSXElementConstructor<any>> \| ComponentRenderFn<HTMLProps, TabsListState>` |  | Allows you to replace the component's HTML element with a different tag, or compose it with another component.  Accepts a `ReactElement` or a function that returns the element to render. |
| variant | `"line" \| "default" \| null` | `default` | `default` is a bordered track whose active tab takes the selection colors, the same control as a segmented ToggleGroup; `line` is a full-width bar on a bottom rule, with the active tab underlined, for page headers, sheets and status pivots. |

### TabsTrigger

| Prop | Type | Default | Description |
| --- | --- | --- | --- |
| disabled | `boolean` |  | Whether the Tab is disabled.  If a first Tab on a `<Tabs.List>` is disabled, it won't initially be selected. Instead, the next enabled Tab will be selected. However, it does not work like this during server-side rendering, as it is not known during pre-rendering which Tabs are disabled. To work around it, ensure that `defaultValue` or `value` on `<Tabs.Root>` is set to an enabled Tab's value. |
| nativeButton | `boolean` | `true` | Whether the component renders a native `<button>` element when replacing it via the `render` prop. Set to `false` if the rendered element is not a button (for example, `<div>`). |
| render | `ReactElement<unknown, string \| JSXElementConstructor<any>> \| ComponentRenderFn<HTMLProps, TabsTabState>` |  | Allows you to replace the component's HTML element with a different tag, or compose it with another component.  Accepts a `ReactElement` or a function that returns the element to render. |
| value (required) | `any` |  | The value of the Tab. |

### TabsContent

| Prop | Type | Default | Description |
| --- | --- | --- | --- |
| keepMounted | `boolean` | `false` | Whether to keep the HTML element in the DOM while the panel is hidden. |
| render | `ReactElement<unknown, string \| JSXElementConstructor<any>> \| ComponentRenderFn<HTMLProps, TabsPanelState>` |  | Allows you to replace the component's HTML element with a different tag, or compose it with another component.  Accepts a `ReactElement` or a function that returns the element to render. |
| value (required) | `any` |  | The value of the TabPanel. It will be shown when the Tab with the corresponding value is active. |

### TabsIndicator

| Prop | Type | Default | Description |
| --- | --- | --- | --- |
| render | `ReactElement<unknown, string \| JSXElementConstructor<any>> \| ComponentRenderFn<HTMLProps, TabsIndicatorState>` |  | Allows you to replace the component's HTML element with a different tag, or compose it with another component.  Accepts a `ReactElement` or a function that returns the element to render. |
| renderBeforeHydration | `boolean` | `false` | Whether to render itself before React hydrates. This minimizes the time that the indicator isn't visible after server-side rendering. |
