Create custom tooltips with Bootstrap. CSS and JavaScript using CSS3 for animations and data-attributes for local title storage.

Points to remember
  • To work with tooltips you must include popper.min.js before bootstrap.js or use bootstrap.bundle.min.js / bootstrap.bundle.jswhich contains Popper.js.
  • You must initialize tooltip manually for performance reasons.
  • Specify container: 'body' to avoid rendering problems in more complex components (like our input groups, button groups, etc).
  • Tooltips with zero-length titles are never displayed and triggering tooltips on hidden elements will not work.
  • Tooltips for .disabled or disabled elements must be triggered on a wrapper element.
  • Tooltips will be centered when triggered from hyperlinks that span multiple lines. To avoid this use white-space: nowrap; on your <a>s.
  • Tooltips must be hidden before their corresponding elements have been removed from the DOM.
How to use
Create a HTML element you wish to have a tooltip and add the required attribute data-toggle="tooltip" attribute and title (add tooltip content to title attribute). By default tooltip is set to top by the plugin. You can customize with data-placement="" attribute.
Initialize tooltip

Initialize all tooltips on a page with javascript $('[data-toggle="tooltip"]').tooltip() by selecting them by their data-toggleattribute.

$(function () {

Tooltip Placements

You can cutomize the tooltip positions with the data-placement=* attributes by adding the values top, right, bottom and left.

And with custom HTML added:

<button type="button" class="btn btn-secondary" data-toggle="tooltip" data-html="true" title="<em>Tooltip</em> <u>with</u> <b>HTML</b>">
  Tooltip with HTML

The tooltip plugin generates content and markup on demand. By default tooltips are placed after their trigger element.

Trigger the tooltip via JavaScript
Overflow auto and scroll

Tooltip position attempts to automatically change when a parent container has overflow: auto or overflow: scroll like our .table-responsive, but still keeps the original placement's positioning. To resolve, set the boundary option to anything other than default value, 'scrollParent', such as 'window':

$('#example').tooltip({ boundary: 'window' })

Always add tooltips to HTML elements which are keyboard-focusable and interactive (such as links or form controls). Arbitrary HTML elements (such as <span>s) can be made focusable by adding the tabindex="0" attribute, but this will be confusing as the tab stops on non-interactive elements and also most assistive technologies do not announce the tooltip in this situation.

<!-- HTML to write -->
<a href="#" data-toggle="tooltip" title="Some tooltip text!">Hover over me</a>

<!-- Generated markup by the plugin -->
<div class="tooltip bs-tooltip-top" role="tooltip">
  <div class="arrow"></div>
  <div class="tooltip-inner">
    Some tooltip text!
Disabled elements

Elements with the disabled attribute are non interactive where users cannot focus, hover, or click them to trigger a tooltip (or popover). So you must trigger the tooltip from a wrapper <div> or <span>, ideally made keyboard-focusable using tabindex="0", and override the pointer-events on the disabled element.


You can set the options via data attributes or JavaScript. For data attributes, append the option name to data-, as in data-animation="".

For individual tooltips you can set options data attribute.

Name Type Default Description
animation boolean true Apply a CSS fade transition to the tooltip
container string | element | false false

Appends the tooltip to a specific element. Example: container: 'body'. This option is particularly useful in that it allows you to position the tooltip in the flow of the document near the triggering element - which will prevent the tooltip from floating away from the triggering element during a window resize.

delay number | object 0

Delay showing and hiding the tooltip (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

Allow HTML in the tooltip.

If true, HTML tags in the tooltip's title will be rendered in the tooltip. 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 tooltip - auto | top | bottom | left | right. When auto is specified, it will dynamically reorient the tooltip.

When a function is used to determine the placement, it is called with the tooltip DOM node as its first argument and the triggering element DOM node as its second. The this context is set to the tooltip instance.

selector string | false false If a selector is provided, tooltip 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="tooltip" role="tooltip"><div class="arrow"></div><div class="tooltip-inner"></div></div>'

Base HTML to use when creating the tooltip.

The tooltip's title will be injected into the .tooltip-inner.

.arrow will become the tooltip's arrow.

The outermost wrapper element should have the .tooltipclass and role="tooltip".

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 tooltip is attached to.

trigger string 'hover focus'

How tooltip is triggered - click | hover | focus | manual. You may pass multiple triggers; separate them with a space.

'manual' indicates that the tooltip will be triggered programmatically via the .tooltip('show'), .tooltip('hide')and .tooltip('toggle') methods; this value cannot be combined with any other trigger.

'hover' on its own will result in tooltips that cannot be triggered via the keyboard, and should only be used if alternative methods for conveying the same information for keyboard users is present.

offset number | string 0 Offset of the tooltip relative to its target. For more information refer to Popper.js's offset docs.
fallbackPlacement string | array 'flip' Allow to specify which position Popper will use on fallback. For more information refer to Popper.js's behavior docs
boundary string | element 'scrollParent' Overflow constraint boundary of the tooltip. Accepts the values of 'viewport', 'window', 'scrollParent', or an HTMLElement reference (JavaScript only). For more information refer to Popper.js's preventOverflow docs.

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.


Attaches a tooltip handler to an element collection.


Reveals an element's tooltip. Returns to the caller before the tooltip has actually been shown (i.e. before the event occurs). This is considered a “manual” triggering of the tooltip. Tooltips with zero-length titles are never displayed.



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



Toggles an element's tooltip. Returns to the caller before the tooltip has actually been shown or hidden (i.e. before the or event occurs). This is considered a “manual” triggering of the tooltip.



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



Gives an element's tooltip the ability to be shown. Tooltips are enabled by default.



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



Toggles the ability for an element's tooltip to be shown or hidden.



Updates the position of an element's tooltip.

Event Type Description This event fires immediately when the show instance method is called. This event is fired when the tooltip has been made visible to the user (will wait for CSS transitions to complete). This event is fired immediately when the hide instance method has been called. This event is fired when the tooltip has finished being hidden from the user (will wait for CSS transitions to complete). This event is fired after the event when the tooltip template has been added to the DOM.
$('#myTooltip').on('', function () {
