Bootstrap Popover

The Popover component is a lot like the tooltips. It appears as a pop-up box when you click a certain component on the page.

However, a popover can contain more content than a usual tooltip element. Here, we will study the creation and controlling of the popover component in Bootstrap.

Toggle popover

For creating a popover, we need to add the data-toggle=”popover” attribute to the desired element.

The header of the popover can be specified using the title attribute. The data-content attribute can be used for the popover body.

jQuery is required to enable the popovers on a page. You can call the popover() method for this. See the code for example:

Positioning Popovers

The popovers are positioned right to the target element, by default.

You can use the data-placement attribute for changing the position to top, bottom, left or the right side of the element.

Check the below code snippets for examples:

Closing Popovers

Closing of popovers can also be controlled.

By default, it gets closed when you click on the target element again.

To close it by clicking anywhere outside the element, you can use the data-trigger=”focus” attribute. See the code below:

Setting data-trigger attribute with a value of “hover” will make the popover appear when you hover over the target element.

Check the following code for the same:
