## Best for

A ghost bell button with an unread dot whose hint gives the new count above a View all link

## Agent notes

- The View all `href` is # and 3 new notifications is fixed text; point the link at your inbox and bind the count

## When not to use

- A numbered count on the trigger with the latest items listed in the hint: use [Bell With Count](https://reui.io/components/tooltip/c-tooltip-5.md) (`get_example("c-tooltip-5")`)

## Install

```bash
npx shadcn@latest add @reui/c-tooltip-16
```

## About Shadcn Tooltip

### When to use

- Short labels for buttons and icon only toolbar actions, with a keyboard shortcut where one exists
- Help text on an info icon, a warning, a verified mark, a locked feature or a disabled button
- Compact summaries behind a trigger, such as service status, notifications, file details or a person

### When not to use

- Content with links or buttons that keyboard users must be able to reach: use [Popover](https://reui.io/components/popover.md) (`get_component("popover")`)
- A rich profile or page preview with a large photo, bio and dates: use [Hover Card](https://reui.io/components/hover-card.md) (`get_component("hover-card")`)
- A status or count that stays readable without pointing at anything: use [Badge](https://reui.io/components/badge.md) (`get_component("badge")`)

### Agent notes

- Outside a `TooltipProvider` the base `Tooltip` opens after 600ms and inside one at once; the radix `Tooltip` throws without one
- `TooltipTrigger` renders a `button` of its own, so a `Button` nested in it without `render` or radix `asChild` makes a button in a button
- `TooltipContent` is portaled to the end of the body with no focus guards, so a link or button in it is not next in Tab order after its trigger
