How Can I Make Bootstrap Dropdowns Appear on Hover Instead of Click?

Hovering Over Bootstrap Menu for Dropdown Instead of Clicking

When using Twitter's Bootstrap framework, by default, menu options appear as dropdown menus when users click on the titles. However, it's possible to modify this behavior so that the menus automatically drop down when users hover over the titles instead.

CSS Customization for Hover Dropdown

To enable hovering for the dropdown menu, you can utilize CSS to override the default settings. The appropriate CSS selector would be:

ul.nav li.dropdown:hover > ul.dropdown-menu {
    display: block;
}

This code ensures that the hidden dropdown menu (represented by ul.dropdown-menu) is displayed as a block element when its associated list item (li.dropdown) is hovered over.

Hiding the Dropdown Arrow

In addition to enabling hover functionality, you may want to hide the small arrows (carets) that appear next to the menu titles. The appropriate steps vary depending on the version of Bootstrap you are using:

Bootstrap 3

Remove the following HTML code from the dropdown toggle anchor element:

<b>caret</b>

Bootstrap 2 and Lower

Utilize the CSS selector and code below to target and remove the arrows:

a.menu:after, .dropdown-toggle:after {
    content: none;
}

By implementing these CSS modifications, you can enhance the usability of your Bootstrap menu by allowing users to access dropdown options more conveniently.
