# Popover: With a calendar

> Use `className="w-auto p-0"` to fit content that brings its own padding. The popup follows the calendar as it changes months.

Example: https://hextaui.com/docs/popover/examples/calendar
Component docs: https://hextaui.com/docs/popover.md

## Add this example

```bash
npx shadcn@latest add https://hextaui.com/r/popover-calendar.json
```

This adds `components/examples/popover/calendar.tsx` with the Popover component and the HextaUI theme tokens.

  const [open, setOpen] = React.useState(false)

  return (
    <Popover open={open} onOpenChange={setOpen}>
      <PopoverTrigger render={<Button variant="outline" />}>
        <IconCalendar />
        {date ? format(date, "PPP") : "Pick a date"}
