## Default markup

To create a default popover use:

<Example centered>
<button type="button" class="btn" data-bs-toggle="popover" title="Popover title" data-bs-content="And here's some amazing content. It's very engaging. Right?"> Click to toggle popover </button>
</Example>

## Four directions

Four options are available: `top`, `right`, `bottom`, and `left` aligned. Directions are mirrored when using Bootstrap in [RTL](/ui/getting-started/rtl).

<Example centered>
<div class="btn-list">
  <button type="button" class="btn" data-bs-container="body" data-bs-toggle="popover" data-bs-placement="top" data-bs-content="Top popover"> Popover on top </button>
  <button type="button" class="btn" data-bs-container="body" data-bs-toggle="popover" data-bs-placement="right" data-bs-content="Right popover"> Popover on right </button>
  <button type="button" class="btn" data-bs-container="body" data-bs-toggle="popover" data-bs-placement="bottom" data-bs-content="Bottom popover"> Popover on bottom </button>
  <button type="button" class="btn" data-bs-container="body" data-bs-toggle="popover" data-bs-placement="left" data-bs-content="Left popover"> Popover on left </button>
</div>
</Example>

## Popover on hover

A popover can open on `click`, `hover`, `focus` or `manual`, set with `data-bs-trigger`. This one opens on hover. See the [Bootstrap documentation](https://getbootstrap.com/docs) for the details.

<Example centered>
<button type="button" class="btn btn-primary" data-bs-trigger="hover" data-bs-toggle="popover" title="Popover title" data-bs-content="And here's some amazing content. It's very engaging. Right?"> Hover to toggle popover </button>
</Example>

## JavaScript

Tabler automatically initializes all elements with `data-bs-toggle="popover"` on page load. This is the code that runs:

<CodeDocs name="popover-init" file="core/js/src/popover.ts" />

To use your own options, create the instance yourself. It replaces the one Tabler created, so only your options apply:

```js
const el = document.getElementById('my-popover');
new tabler.Popover(el, { customClass: 'popover-wide', trigger: 'focus' });
```

To read or control the existing instance without changing its options, use `tabler.Popover.getInstance(el)` or `tabler.Popover.getOrCreateInstance(el)`.

## Accessibility

- The trigger must be a `button` or a link with an `href`, so it can take focus. Bootstrap manages `aria-describedby` while the popover is open.
- Popovers open on click by default, which is what makes their content reachable. If you switch to `data-bs-trigger="hover"`, the content becomes unreachable by keyboard.
- Set `data-bs-trigger="focus"` to make a popover dismiss itself when focus leaves, which is the closest thing to <kbd>Escape</kbd> behavior.
- Tabler enables HTML in a popover only when you set `data-bs-html="true"`. Leave it off for content that comes from users.
- Keep the title and body as text. A popover holding a form is a modal in disguise - use a real dialog for that.
