Conceal the .dropdown-backdrop from bootstrap using solely CSS styling techniques

Is there a way to hide the .dropdown-backdrop element from Bootstrap for a specific dropdown on a webpage using only CSS?

I found a solution that involves Javascript, you can view it on JSFiddle here. However, I am hoping to achieve this without relying on additional JS code.

<!-- First dropdown: no backdrop -->
<div id="firstDropdown" class="dropdown">
    <button class="btn-dropdown-add btn btn-blue" data-toggle="dropdown">
        First Dropdown &#x25BC;
    </button>
    <ul class="dropdown-menu" role="menu">
        <li><a class="a_dropdown_item" href="#business">Business</a></li>
        <li><a class="a_dropdown_item" href="#my-events">Event</a></li>
    </ul>
</div>

<!-- Second dropdown: yes backdrop -->
<div id="secondDropdown" class="dropdown">
    <button class="btn-dropdown-add btn btn-blue" data-toggle="dropdown">
        Second Dropdown &#x25BC;
    </button>
    <ul class="dropdown-menu" role="menu">
        <li><a class="a_dropdown_item" href="#business">Business</a></li>
        <li><a class="a_dropdown_item" href="#my-events">Event</a></li>
    </ul>
</div>

<script type="text/javascript">
    // Hide backdrop from #firstDropdown.
    // This can be done with JS as below. Can it be done with only CSS?
    $('#firstDropdown').on('show.bs.dropdown', function () {
      $(".dropdown-backdrop").hide();
    });
</script>

Answer №1

Solution discovered: the .dropdown-backdrop element is a child of its parent .dropdown, which can be identified by a unique ID. Therefore, simply utilizing display:none; in CSS effectively hides it, like so:

#firstDropdown .dropdown-backdrop {
    display:none;
}

All other dropdowns (excluding #firstDropdown) will still maintain their backdrop as usual.
