# Popover

Displays rich content in a portal, triggered by a button.

## When to use

* Show a small form or details next to the button that opened it.
* Hold content that needs interaction, which a tooltip cannot.

## How it works

Parts: `Popover`, `PopoverTrigger`, `PopoverContent`, `PopoverHeader`, `PopoverTitle` and `PopoverDescription`. With Base UI it wraps `@base-ui/react/popover`; with Radix, `Popover` from `radix-ui`, which adds `PopoverAnchor`. The content opens in a portal.

## Example

### Base UI

```tsx
'use client'

import { Button } from "@/shadcn/base/ui/button"
import { Input } from "@/shadcn/base/ui/input"
import { Label } from "@/shadcn/base/ui/label"
import {
  Popover,
  PopoverContent,
  PopoverTrigger,
} from "@/shadcn/base/ui/popover"

export default function PopoverDemo() {
  return (
    <Popover>
      <PopoverTrigger render={<Button variant="outline" />}>
        Open popover
      </PopoverTrigger>
      <PopoverContent className="w-80">
        <div className="grid gap-4">
          <div className="space-y-2">
            <h4 className="leading-none font-medium">Dimensions</h4>
            <p className="text-sm text-muted-foreground">
              Set the dimensions for the layer.
            </p>
          </div>
          <div className="grid gap-2">
