## Overview
Things to know when using the popover plugin:
- Popovers rely on the 3rd party library [Popper.js](https://popper.js.org/) for positioning. You must include [popper.min.js]({{< param "cdn.popper" >}}) before bootstrap.js or use `bootstrap.bundle.min.js` / `bootstrap.bundle.js` which contains Popper.js in order for popovers to work!
- Popovers require the [tooltip plugin]({{< docsref "/components/tooltips" >}}) as a dependency.
- Popovers are opt-in for performance reasons, so **you must initialize them yourself**.
- Zero-length `title` and `content` values will never show a popover.
- Specify `container: 'body'` to avoid rendering problems in more complex components (like our input groups, button groups, etc).
- Triggering popovers on hidden elements will not work.
- Popovers for `.disabled` or `disabled` elements must be triggered on a wrapper element.
- When triggered from anchors that wrap across multiple lines, popovers will be centered between the anchors' overall width. Use `.text-nowrap` on your `<a>`s to avoid this behavior.
- Popovers must be hidden before their corresponding elements have been removed from the DOM.
- Popovers can be triggered thanks to an element inside a shadow DOM.

## Example: Enable popovers everywhere
One way to initialize all popovers on a page would be to select them by their `data-toggle` attribute:

{{< highlight js >}}
var popoverTriggerList = [].slice.call(document.querySelectorAll('[data-toggle="popover"]'))
var popoverList = popoverTriggerList.map(function (popoverTriggerEl) {
return new bootstrap.Popover(popoverTriggerEl)
})
{{< /highlight >}}

## Example: Using the `container` option
2015-08-10 05:28:46 +02:00
When you have some styles on a parent element that interfere with a popover, you'll want to specify a custom `container` so that the popover's HTML appears within that element instead.
{{< highlight js >}}
var popover = new bootstrap.Popover(document.querySelector('.example-popover'), {
container: 'body'
})
{{< /highlight >}}

### Dismiss on next click
2014-07-13 09:54:34 +02:00
Use the `focus` trigger to dismiss popovers on the user's next click of a different element than the toggle element.
2014-07-13 09:54:34 +02:00
{{< callout danger >}}
#### Specific markup required for dismiss-on-next-click
For proper cross-browser and cross-platform behavior, you must use the `<a>` tag, _not_ the `<button>` tag, and you also must include a [`tabindex`](https://developer.mozilla.org/en-US/docs/Web/HTML/Global_attributes/tabindex) attribute.

{{< example >}}
<a tabindex="0" class="btn btn-lg btn-danger" role="button" data-toggle="popover" data-trigger="focus" title="Dismissible popover" data-content="And here's some amazing content. It's very engaging. Right?">Dismissible popover</a>

trigger: 'focus'
})
{{< /highlight >}}
2014-03-17 03:03:53 +01:00
### Disabled elements
Elements with the `disabled` attribute aren't interactive, meaning users cannot hover or click them to trigger a popover (or tooltip). As a workaround, you'll want to trigger the popover from a wrapper `<div>` or `<span>` and override the `pointer-events` on the disabled element.
For disabled popover triggers, you may also prefer `data-trigger="hover"` so that the popover appears as immediate visual feedback to your users as they may not expect to _click_ on a disabled element.
{{< example >}}
<span class="d-inline-block" data-toggle="popover" data-content="Disabled popover">
<button class="btn btn-primary" style="pointer-events: none;" type="button" disabled>Disabled button</button>
</span>
{{< /example >}}
2014-03-17 03:03:53 +01:00
2014-07-13 09:54:34 +02:00
## Usage
Enable popovers via JavaScript:
{{< highlight js >}}
var exampleEl = document.getElementById('example')
var popover = new bootstrap.Popover(exampleEl, options)
{{< /highlight >}}

### Making popovers work for keyboard and assistive technology users
To allow keyboard users to activate your popovers, you should only add them to HTML elements that are traditionally keyboard-focusable and interactive (such as links or form controls). Although arbitrary HTML elements (such as `<span>`s) can be made focusable by adding the `tabindex="0"` attribute, this will add potentially annoying and confusing tab stops on non-interactive elements for keyboard users, and most assistive technologies currently do not announce the popover's content in this situation. Additionally, do not rely solely on `hover` as the trigger for your popovers, as this will make them impossible to trigger for keyboard users.
While you can insert rich, structured HTML in popovers with the `html` option, we strongly recommend that you avoid adding an excessive amount of content. The way popovers currently work is that, once displayed, their content is tied to the trigger element with the `aria-describedby` attribute. As a result, the entirety of the popover's content will be announced to assistive technology users as one long, uninterrupted stream.
Additionally, while it is possible to also include interactive controls (such as form elements or links) in your popover (by adding these elements to the `whiteList` or allowed attributes and tags), be aware that currently the popover does not manage keyboard focus order. When a keyboard user opens a popover, focus remains on the triggering element, and as the popover usually does not immediately follow the trigger in the document's structure, there is no guarantee that moving forward/pressing <kbd>TAB</kbd> will move a keyboard user into the popover itself. In short, simply adding interactive controls to a popover is likely to make these controls unreachable/unusable for keyboard users and users of assistive technologies, or at the very least make for an illogical overall focus order. In these cases, consider using a modal dialog instead.

### Options
Options can be passed via data attributes or JavaScript. For data attributes, append the option name to `data-`, as in `data-animation=""`.
{{< callout warning >}}
Note that for security reasons the `sanitize`, `sanitizeFn` and `whiteList` options cannot be supplied using data attributes.

Reveals an element's popover. **Returns to the caller before the popover has actually been shown** (i.e. before the `shown.bs.popover` event occurs). This is considered a "manual" triggering of the popover. Popovers whose title and content are both zero-length are never displayed.

2014-07-13 09:54:34 +02:00
Toggles an element's popover. **Returns to the caller before the popover has actually been shown or hidden** (i.e. before the `shown.bs.popover` or `hidden.bs.popover` event occurs). This is considered a "manual" triggering of the popover.

2014-07-13 09:54:34 +02:00
#### dispose
