# Tabs
A high-quality, unstyled Solid tabs component for toggling between related panels on the same page.
## Demo
### Tailwind
This example shows how to implement the component using Tailwind CSS.
```tsx
/* index.tsx */
import { Tabs } from 'base-ui-solid/tabs';
const tabClassName =
'flex h-[calc(2rem+1px)] items-center justify-center bg-transparent px-2 py-0 font-inherit text-sm font-normal leading-5 break-keep whitespace-nowrap text-neutral-600 outline-none select-none hover:text-neutral-950 focus-visible:outline-2 focus-visible:outline-solid focus-visible:-outline-offset-1 focus-visible:outline-neutral-950 dark:focus-visible:outline-white data-active:text-neutral-950 dark:text-neutral-300 dark:hover:text-white dark:data-active:text-white';
const panelClassName =
'col-start-1 row-start-1 flex w-full items-center justify-center bg-white p-4 text-center text-sm text-neutral-950 outline-none focus-visible:z-1 focus-visible:outline-2 focus-visible:outline-solid focus-visible:-outline-offset-1 focus-visible:outline-neutral-950 dark:focus-visible:outline-white dark:bg-neutral-950 dark:text-white [[hidden]]:hidden';
export default function ExampleTabs() {
return (
Overview
Projects
Account
);
}
```
## Anatomy
Import the component and assemble its parts:
```jsx title="Anatomy"
import { Tabs } from 'base-ui-solid/tabs';
;
```
## Examples
### Animated panels
Animate panels as they activate using the `data-starting-style` and `data-ending-style` attributes.
The `data-activation-direction` attribute indicates which direction the newly active tab is relative to the previously active one, letting panels slide in from the correct side.

### Tailwind
This example shows how to implement the component using Tailwind CSS.
```tsx
/* index.tsx */
import { Tabs } from 'base-ui-solid/tabs';
export default function ExampleAnimatedTabs() {
return (
Overview
Projects
Account
);
}
```
### Links
Use the `render` prop and set `nativeButton={false}` on `` to render tabs as anchor elements.
```jsx title="Tabs as links"
import { Tabs } from 'base-ui-solid/tabs';
import Link from 'next/link';
{/* @highlight-start */}
{/* @highlight-text "nativeButton={false}" "render" */}
}
value="overview"
>
Overview
{/* @highlight-end */}
{/* ... */}
;
```
## API reference
### Root
Groups the tabs and the corresponding panels.
Renders a `
` element.
**Root Props:**
| Name | Type | Default | Description |
| ------------- | ------------------------------------------------------------------------------------ | -------------- | --------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- |
| defaultValue | Tabs.Tab.Value | `0` | The default value. Use when the component is not controlled. When the value is `null`, no Tab will be active. |
| value | Tabs.Tab.Value | - | The value of the currently active `Tab`. Use when the component is controlled. When the value is `null`, no Tab will be active. |
| onValueChange | ((value: Tabs.Tab.Value, eventDetails: Tabs.Root.ChangeEventDetails) => 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 | Tabs.Root.Orientation | `'horizontal'` | The component orientation (layout flow direction). |
| class | JSX.ClassValue \| ((state) => JSX.ClassValue) | - | CSS class applied to the element, or a function that returns a class based on the component's state. |
| style | JSX.CSSProperties \| string \| ((state) => JSX.CSSProperties \| string \| undefined) | - | Style applied to the element, or a function that returns a style object based on the component's state. |
| render | keyof JSX.IntrinsicElements \| Component \| ((props, state) => JSX.Element) | - | Replace the default element with a tag name, component, or render function. |
**Root Data Attributes:**
