Bootstrap popovers

Bootstrap popover is a component which displays a box with a content and is similar to this found in iOS. It is comparable to the tooltips but can contain more content. Popovers are usualy activated with a click and can be easily applied to any element on your site.

Overview

Things to know when using the popover plugin:

  • Popovers rely on the 3rd party library Popper.js for positioning. You must include popper.min.js before bootstrap.js in order for popovers to work!
  • 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 hyperlinks that span multiple lines, popovers will be centered. Use white-space: nowrap; on your <a>s to avoid this behavior.
  • Popovers must be hidden before their corresponding elements have been removed from the DOM.

Keep reading to see how popovers work with some examples.


Initialization

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

// popovers Initialization
$(function () {
    $('[data-toggle="popover"]').popover()
})

There can be a situation, when you have some styles on a parent element that interfere with a popover. Then you’ll need to specify a custom container so that the popover’s HTML appears within that element instead.

// popovers Initialization
$(function () {
    $('.example-popover').popover({
        container: 'body'
    })
})

Examples

Here are some ways to customize User Experience using popovers.

Four directions

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

<button type="button" class="btn btn-default" data-toggle="popover" data-placement="top" title="popover on top" data-content="Sed posuere consectetur est at lobortis. Aenean eu leo quam. Pellentesque ornare sem lacinia quam venenatis vestibulum.">popover on top</button>

<button type="button" class="btn btn-default" data-toggle="popover" data-placement="right" title="popover on right" data-content="Sed posuere consectetur est at lobortis. Aenean eu leo quam. Pellentesque ornare sem lacinia quam venenatis vestibulum.">popover on right</button>

<button type="button" class="btn btn-default" data-toggle="popover" data-placement="bottom" title="popover on bottom" data-content="Sed posuere consectetur est at lobortis. Aenean eu leo quam. Pellentesque ornare sem lacinia quam venenatis vestibulum.">popover on bottom</button>

<button type="button" class="btn btn-default" data-toggle="popover" data-placement="left" title="popover on left" data-content="Sed posuere consectetur est at lobortis. Aenean eu leo quam. Pellentesque ornare sem lacinia quam venenatis vestibulum.">popover on left</button>

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.

Dismissible popover
<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>
$('.popover-dismiss').popover({
    trigger: 'focus'
})

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.

<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>

Usage

The popover plugin generates content and markup on demand and by default places popovers after their trigger element.

Trigger the popover via JavaScript:

$('#example').popover(options)

Options

As we have already seen in the "Dismiss on next click" example, popover 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
boundary string | element 'scrollParent' Overflow constraint boundary of the popover. Accepts the values of 'viewport', 'window', 'scrollParent', or an HTMLElement reference (JavaScript only). For more information refer to Popper.js's preventOverflow docs.
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 | element | 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.

constraints Array [] An array of constraints - passed through to Tether. For more information refer to Tether's constraint docs.
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 'top'

How to position the popover - auto | top | bottom | left | right. When auto is specified, it will dynamically reorient the popover.

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="popover"><div class="popover-arrow"></div><div class="popover-inner"></div></div>'

Base HTML to use when creating the popover.

The popover's title will be injected into the .popover-header.

The popover's content will be injected into the .popover-body.

.arrow will become the popover's arrow.

The outermost wrapper element should have the .popover class.

title string | element | 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 'hover focus' How popover is triggered - click | hover | focus | manual. You may pass multiple triggers; separate them with a space. `manual` cannot be combined with any other trigger.
offsets string '0 0' Offset of the popover relative to its target. For more information refer to Tether's offset docs.

Data attributes for individual popovers

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


Methods

Asynchronous methods and transitions

All API methods are asynchronous and start a transition. They return to the caller as soon as the transition is started but before it ends. In addition, a method call on a transitioning component will be ignored.

$().popover(options)

Attaches a popover handler to an element collection.


.popover('show')

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 with zero-length titles are never displayed.

$('#element').popover('show')

.popover('hide')

Hides an element’s popover. Returns to the caller before the popover has actually been hidden (i.e. before the hidden.bs.popover event occurs). This is considered a “manual” triggering of the popover.

$('#element').popover('hide')

.popover('toggle')

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.

$('#element').popover('toggle')

.popover('dispose')

Hides and destroys an element’s popover. popovers that use delegation (which are created using the selector option) cannot be individually destroyed on descendant trigger elements.

$('#element').popover('dispose')

.popover('enable')

Gives an element’s popover the ability to be shown. Popovers are enabled by default.

$('#element').popover('enable')

.popover('disable')

Removes the ability for an element’s popover to be shown. The popover will only be able to be shown if it is re-enabled.

$('#element').popover('disable')

.popover('toggleEnabled')

Toggles the ability for an element’s popover to be shown or hidden.

$('#element').popover('toggleEnabled')

.popover('updateupdate')

Updates the position of an element’s popover.

$('#element').popover('update')

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).
inserted.bs.popover This event is fired after the show.bs.popover event when the popover template has been added to the DOM.
$('#mypopover').on('hidden.bs.popover', function () {
// do something…
})
