layout	title
page	Popovers

Add small overlays of content, like those on the iPad, to any element for housing secondary information.

Popovers whose both title and content are zero-length are never displayed.

Plugin dependency

Popovers require the tooltip plugin to be included in your version of Bootstrap.

Opt-in functionality

For performance reasons, the Tooltip and Popover data-apis are opt-in, meaning you must initialize them yourself.

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

{% highlight js %} $(function () { $('[data-toggle="popover"]').popover() }) {% endhighlight %}

Popovers in button groups and input groups require special setting

When using popovers on elements within a .btn-group or an .input-group, you'll have to specify the option container: 'body' (documented below) to avoid unwanted side effects (such as the element growing wider and/or losing its rounded corners when the popover is triggered).

Don't try to show popovers on hidden elements

Invoking $(...).popover('show') when the target element is display: none; will cause the popover to be incorrectly positioned.

Popovers on disabled elements require wrapper elements

To add a popover to a disabled or .disabled element, put the element inside of a <div> and apply the popover to that <div> instead.

Multiple-line links

Sometimes you want to add a popover to a hyperlink that wraps multiple lines. The default behavior of the popover plugin is to center it horizontally and vertically. Add white-space: nowrap; to your anchors to avoid this.

Static popover

Four options are available: top, right, bottom, and left aligned.

Popover top

Sed posuere consectetur est at lobortis. Aenean eu leo quam. Pellentesque ornare sem lacinia quam venenatis vestibulum.

Popover right

Sed posuere consectetur est at lobortis. Aenean eu leo quam. Pellentesque ornare sem lacinia quam venenatis vestibulum.

Popover bottom

<div class="popover-content">
  <p>Sed posuere consectetur est at lobortis. Aenean eu leo quam. Pellentesque ornare sem lacinia quam venenatis vestibulum.</p>
</div>

Popover left

Sed posuere consectetur est at lobortis. Aenean eu leo quam. Pellentesque ornare sem lacinia quam venenatis vestibulum.

Live demo

{% example html %} Click to toggle popover {% endexample %}

Four directions

Popover on left Popover on top Popover on bottom Popover on right

{% highlight html %} Popover on left

Popover on top

Popover on bottom

Popover on right {% endhighlight %}

Dismiss on next click

Use the focus trigger to dismiss popovers on the next click that the user makes.

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 attribute.

{% example html %} Dismissible popover {% endexample %}

{% highlight js %} $('.popover-dismiss').popover({ trigger: 'focus' }) {% endhighlight %}

Usage

Enable popovers via JavaScript:

{% highlight js %}$('#example').popover(options){% endhighlight %}

Options

Options can be passed via data attributes or JavaScript. For data attributes, append the option name to data-, as in data-animation="".

Name	Type	Default	Description
animation	boolean	true	Apply a CSS fade transition to the popover
container	string | false	false	Appends the popover to a specific element. Example: container: 'body'. This option is particularly useful in that it allows you to position the popover in the flow of the document near the triggering element - which will prevent the popover from floating away from the triggering element during a window resize.
content	string | function	''	Default content value if data-content attribute isn't present. If a function is given, it will be called with its this reference set to the element that the popover is attached to.
delay	number | object	0	Delay showing and hiding the popover (ms) - does not apply to manual trigger type If a number is supplied, delay is applied to both hide/show Object structure is: delay: { "show": 500, "hide": 100 }
html	boolean	false	Insert HTML into the popover. If false, jQuery's text method will be used to insert content into the DOM. Use text if you're worried about XSS attacks.
placement	string | function	'right'	How to position the popover - top | bottom | left | right | auto. When "auto" is specified, it will dynamically reorient the popover. For example, if placement is "auto left", the popover will display to the left when possible, otherwise it will display right. When a function is used to determine the placement, it is called with the popover DOM node as its first argument and the triggering element DOM node as its second. The this context is set to the popover instance.
selector	string	false	If a selector is provided, popover objects will be delegated to the specified targets. In practice, this is used to enable dynamic HTML content to have popovers added. See this and an informative example.
template	string	'<div class="popover" role="tooltip"><div class="arrow"></div><h3 class="popover-title"></h3><div class="popover-content"></div></div>'	Base HTML to use when creating the popover. The popover's title will be injected into the .popover-title. The popover's content will be injected into the .popover-content. .arrow will become the popover's arrow. The outermost wrapper element should have the .popover class.
title	string | function	''	Default title value if title attribute isn't present. If a function is given, it will be called with its this reference set to the element that the popover is attached to.
trigger	string	'click'	How popover is triggered - click | hover | focus | manual. You may pass multiple triggers; separate them with a space.
viewport	string | object	{ selector: 'body', padding: 0 }	Keeps the popover within the bounds of this element. Example: viewport: '#viewport' or { "selector": "#viewport", "padding": 0 }

Data attributes for individual popovers

Options for individual popovers can alternatively be specified through the use of data attributes, as explained above.

Methods

$().popover(options)

Initializes popovers for an element collection.

.popover('show')

Reveals an element's popover. Popovers whose both title and content are zero-length are never displayed.

{% highlight js %}$('#element').popover('show'){% endhighlight %}

.popover('hide')

Hides an element's popover.

{% highlight js %}$('#element').popover('hide'){% endhighlight %}

.popover('toggle')

Toggles an element's popover.

{% highlight js %}$('#element').popover('toggle'){% endhighlight %}

.popover('destroy')

Hides and destroys an element's popover.

{% highlight js %}$('#element').popover('destroy'){% endhighlight %}

Events

Event Type	Description
show.bs.popover	This event fires immediately when the show instance method is called.
shown.bs.popover	This event is fired when the popover has been made visible to the user (will wait for CSS transitions to complete).
hide.bs.popover	This event is fired immediately when the hide instance method has been called.
hidden.bs.popover	This event is fired when the popover has finished being hidden from the user (will wait for CSS transitions to complete).

{% highlight js %} $('#myPopover').on('hidden.bs.popover', function () { // do something… }) {% endhighlight %}
