Bootstrap 4 Tooltips

A tooltip is a small pop-up that appears when the mouse is moved over an element and disappears when the mouse is moved away.

How to Create a Tooltip

Create a tooltip by adding data-toggle="tooltip" to an element.

The content of the title attribute is what will be displayed in the tooltip:

<a href="#" data-toggle="tooltip" title="I am the tooltip content!">Hover over me</a>

Note: Tooltips must be initialized with jQuery: call the tooltip() method on the specified element.

The following example allows tooltips to be used anywhere in the document:

Example

$(document).ready(function(){
    $('[data-toggle="tooltip"]').tooltip(); 
});

Specifying Tooltip Position

By default, the tooltip appears above the element.

You can use the data-placement attribute to set the direction of the tooltip: top, bottom, left, or right:

Example

<a href="#" data-toggle="tooltip" data-placement="top" title="I am the tooltip content!">Hover over me</a>
<a href="#" data-toggle="tooltip" data-placement="bottom" title="I am the tooltip content!">Hover over me</a>
<a href="#" data-toggle="tooltip" data-placement="left" title="I am the tooltip content!">Hover over me</a>
<a href="#" data-toggle="tooltip" data-placement="right" title="I am the tooltip content!">Hover over me</a>

Using tooltips in buttons:

Example

<button type="button" class="btn btn-secondary" data-toggle="tooltip" data-placement="top" title="Tooltip on top">
  Tooltip on top
</button>
<button type="button" class="btn btn-secondary" data-toggle="tooltip" data-placement="right" title="Tooltip on right">
  Tooltip on right
</button>
<button type="button" class="btn btn-secondary" data-toggle="tooltip" data-placement="bottom" title="Tooltip on bottom">
  Tooltip on bottom
</button>
<button type="button" class="btn btn-secondary" data-toggle="tooltip" data-placement="left" title="Tooltip on left">
  Tooltip on left
</button>

To add HTML tags to the tooltip content, set data-html="true" and place the content inside the title attribute:

Example

<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
</button>

Disabling a button:

Example

<span class="d-inline-block" tabindex="0" data-toggle="tooltip" title="Disabled tooltip">
  &lt;button class="btn btn-primary" style="pointer-events: none;" type="button" disabled>Disabled button</button>
</span>
