  • Show contextual actions or details without navigating away from the current view.
  • Present a small form or filter near the control that opens it.
  • Add supplementary information with a heading and description.
  • Use for content that should appear on demand rather than remain in the page layout.

Examples

Account details

Show a person’s name and email in a titled popover.

import {  Popover,  PopoverContent,  PopoverHeader,  PopoverTitle,  PopoverDescription,  PopoverTrigger,} from "@/components/ui/popover"export function AccountDetails() {  return (    <Popover>      <PopoverTrigger>Account details</PopoverTrigger>      <PopoverContent>        <PopoverHeader>          <PopoverTitle>Alex Morgan</PopoverTitle>          <PopoverDescription>alex@example.com</PopoverDescription>        </PopoverHeader>      </PopoverContent>    </Popover>  )}

Date filter

Place a small date input near its trigger and align the panel to the start.

date-filter.tsx
import {  Popover,  PopoverContent,  PopoverHeader,  PopoverTitle,  PopoverDescription,  PopoverTrigger,} from "@/components/ui/popover"export function DateFilter() {  return (    <Popover>      <PopoverTrigger>Filter results</PopoverTrigger>      <PopoverContent align="start" side="bottom">        <PopoverHeader>          <PopoverTitle>Availability</PopoverTitle>          <PopoverDescription>Choose a date range.</PopoverDescription>        </PopoverHeader>        <input aria-label="Start date" type="date" />      </PopoverContent>    </Popover>  )}

Contextual help

Place a concise definition beside its trigger.

contextual-help.tsx
import {  Popover,  PopoverContent,  PopoverHeader,  PopoverTitle,  PopoverDescription,  PopoverTrigger,} from "@/components/ui/popover"export function WorkspaceHelp() {  return (    <Popover>      <PopoverTrigger>What is a workspace?</PopoverTrigger>      <PopoverContent side="right">        <PopoverHeader>          <PopoverTitle>Workspace</PopoverTitle>          <PopoverDescription>A shared place for a team to organize work.</PopoverDescription>        </PopoverHeader>      </PopoverContent>    </Popover>  )}

Accessibility

  • Use meaningful, visible text for the trigger so its purpose is clear.
  • Give the popover a clear title when its content needs a heading; use PopoverTitle and PopoverDescription to provide structured context.
  • For form controls inside the content, provide accessible labels, such as an associated label or an aria-label.
  • The trigger and popup use Base UI primitives; follow their interaction and keyboard behavior, and avoid replacing the trigger with a non-interactive element.
