    Bootstrap Dropdown Hover Build Status

    Bootstrap Dropdown Hover is a simple plugin which opens Bootstrap dropdown menus on mouse hover, the proper way.


    Check the official website for a demo.

    Why I made it, when there are many solutions already?

    I had issues with all the previously existing solutions. The simple CSS ones are not using the .open class on the parent element, so there will be no feedback on the dropdown toggle element when the dropdown menu is visible.

    The js ones are interfering with clicking on .dropdown-toggle, so the dropdown menu shows up on hover, then it is hiding when clicking on the .dropdown-toggle element, and moving out the mouse will trigger the dropdown menu to show up again. Some of the js solutions are braking iOS compatibility, some plugins are not working on modern desktop browsers which are supporting the touch events.

    That's why I made this proper plugin, which prevents all these issues by using only the standard Bootstrap javascript API, without any hack.


    1. Download the latest tag from the releases page or get it via bower:
    $ bower install bootstrap-dropdown-hover
    1. Include jQuery and Bootstrap:
    <link rel="stylesheet" href="//">
    <script src="//"></script>
    <script src="//"></script>
    1. Include plugin's code:
    <script src="dist/jquery.bootstrap-dropdown-hover.min.js"></script>
    1. Call the plugin:

    Initiate on all dropdowns/dropups method 1

      // see next for specifications

    Initiate on all dropdowns/dropups method 1

      // see next for specifications

    Initiate on navbar menu only

    $('.navbar [data-toggle="dropdown"]').bootstrapDropdownHover({
      // see next for specifications


    Initialization parameters object

    When calling bootstrapDropdownHover() you can pass a parameters object with zero or more of the following:

    • clickBehavior, 'sticky'|'default'|'disable'|'link', defaults to sticky, which means that if we click on an opened dropdown then it will not hide on mouseleave but on a second click only. Can be default, which means that means that the dropdown toggles on hover and on click too, disable, which disables dropdown toggling with clicking when mouse is detected (so it will open on hover only) or link which is like disable, but does not prevent the default browser action (i.e. link clicks).
    • hideTimeout, integer, defaults to 200, how much time the hovered dropdown hides after mouseleave (in milliseconds).

    These settings can also be set via HTML5 data attributes on the element itself, e.g. this will override both default and explicit constructor settings:

    <a data-toggle="dropdown" data-click-behavior="default"></a>


    You can modify the behavior of the plugin by calling its methods, all of which accept a value.

    To call methods on any dropdown hover instance, use the following syntax:

    $(selector).bootstrapDropdownHover(methodName, parameter);

    Here are the available methods:

    • setClickBehavior(value) to change the clickBehavior parameter.
    • setHideTimeout(value) to change the hideTimeout parameter.

    Furthermore, you can call:

    • destroy() to restore the original behavior.
