Bootstrap putting checkbox in a dropdown

Here’s what we’ll build:

HTML

Essentially, we’ll look to combine two different sets of Bootstrap controls & styles: Dropdowns & Checkboxes. Inside of each li, we’ll use a label instead of an a element, so that we can wrap the checkbox in a label and make the entire row clickable.

<ul class="dropdown-menu checkbox-menu allow-focus">
  <li >
    <label>
      <input type="checkbox"> Cheese
    </label>
  </li>
</ul>

CSS

We can steal some of the styles normally applied to .dropdown-menu li a, input and apply them to our label option instead. We’ll make the label occupy the full width of the container and fix some label / checkbox alignment issues. Additionally, we’ll add styles for .active and :hover.

.checkbox-menu li label {
    display: block;
    padding: 3px 10px;
    clear: both;
    font-weight: normal;
    line-height: 1.42857143;
    color: #333;
    white-space: nowrap;
    margin:0;
    transition: background-color .4s ease;
}
.checkbox-menu li input {
    margin: 0px 5px;
    top: 2px;
    position: relative;
}

.checkbox-menu li.active label {
    background-color: #cbcbff;
    font-weight:bold;
}

.checkbox-menu li label:hover,
.checkbox-menu li label:focus {
    background-color: #f5f5f5;
}

.checkbox-menu li.active label:hover,
.checkbox-menu li.active label:focus {
    background-color: #b8b8ff;
}

JavaScript

Some other housekeeping, we’ll manually keep an .active class flag on each list item to correspond to whether or not the item is checked so we can style it appropriately.

$(".checkbox-menu").on("change", "input[type="checkbox"]", function() {
   $(this).closest("li").toggleClass("active", this.checked);
});

We’ll also want to allow multiple selections by allowing the menu to stay open on internal click events by stopping the event from bubbling up

$(document).on('click', '.allow-focus', function (e) {
  e.stopPropagation();
});

Demo in Stack Snippets

$(".checkbox-menu").on("change", "input[type="checkbox"]", function() {
   $(this).closest("li").toggleClass("active", this.checked);
});

$(document).on('click', '.allow-focus', function (e) {
  e.stopPropagation();
});

body {
  padding: 15px;
}

.checkbox-menu li label {
    display: block;
    padding: 3px 10px;
    clear: both;
    font-weight: normal;
    line-height: 1.42857143;
    color: #333;
    white-space: nowrap;
    margin:0;
    transition: background-color .4s ease;
}
.checkbox-menu li input {
    margin: 0px 5px;
    top: 2px;
    position: relative;
}

.checkbox-menu li.active label {
    background-color: #cbcbff;
    font-weight:bold;
}

.checkbox-menu li label:hover,
.checkbox-menu li label:focus {
    background-color: #f5f5f5;
}

.checkbox-menu li.active label:hover,
.checkbox-menu li.active label:focus {
    background-color: #b8b8ff;
}
