Dropdown Menu with pure CSS and HTML

Question

I have below CSS for a dropdown menu:

.dropdown {
  position: relative;
  display: inline-block;
}

.dropdown-content {
  display: none;
  position: absolute;
  right: 0;
  top: 30px;
  background-color: #f9f9f9;
  min-width: 160px;
  box-shadow: 0px 8px 16px 0px rgba(0,0,0,0.2);
  z-index: 1;

  button, a {
    border-bottom: 1px solid #e7e7e7;
    border-radius: unset;
    text-align: left;
    display: inline-block;
    width: 100%!important;

    .icon {
      margin-right: 15px;
      top: 0.13em;
    }

    &:hover {
      background-color: #e7e7e7 !important;
    }

    &:active {
      background-color: #c7c7c7 !important;
    }
  }
}

.dropdown:hover .dropdown-content {
  display: block;
}

And below markup:

                <div class="dropdown">
                  <button class="material-icon-button">
                    <i class="icon icon-more_vert"></i>
                  </button>
                  <div class="dropdown-content" style="width: 295px;">
                    <button class="material-button">
                      <i class="icon icon-undo"></i>
                      <span>Button 1</span>
                    </button>
                    <button class="material-button">
                      <i class="icon icon-add_alert"></i>
                      Button 2
                    </button>
                  </div>
                </div>

This works fine and shows menu on mouseover.

What I am trying to achieve is that, instead of mouseover, the dropdown is shown when the user actually clicks the button.

I have tried:

.dropdown:active .dropdown-content {
  display: block;
}

But It doesn't seem to work, it show the menu on click but hides immediately.

I was wondering if this could be done without JavaScript and with pure css? if so, can someone please guide on this.

Thanks

Answer 1

There is a way to handle clicks with pure CSS. It's not the best way (because that's not what CSS is made for) but it should work. Basically you'll have to use a checkbox with a label and style according to the state of the checkbox.
Here is an example: https://css-tricks.com/the-checkbox-hack/

try like below, hope it helps, comment if query

 .c { display: flex; align-items: center; justify-content: center; height:100%; width:100%; }.dd { z-index:1; position:relative; display: inline-block; }.dd-a { padding:10px; background:white; position:relative; box-shadow: 0px 0px 5px 0px rgba(0,0,0,0.75); transition-duration: 0.2s; -webkit-transition-duration: 0.2s; }.dd input:after { content:""; width:100%; height:2px; position:absolute; display:block; background:#C63D0F; bottom:0; left:0; transform: scaleX(0); transform-origin: bottom left; transition-duration: 0.2s; -webkit-transform: scaleX(0); -webkit-transform-origin: bottom left; -webkit-transition-duration: 0.2s; }.dd input { top:0; opacity:0; display:block; padding:0; margin:0; border:0; position:absolute; height:100%; width:100%; }.dd input:hover { cursor:pointer; }.dd input:hover ~.dd-a { box-shadow: 0px 0px 15px 0px rgba(0,0,0,0.75); }.dd input:checked:after { transform: scaleX(1); -webkit-transform: scaleX(1); }.dd input:checked ~.dd-c { transform: scaleY(1); -webkit-transform: scaleY(1); }.dd-a span { color:#C63D0F; }.dd-c{ display:block; position: absolute; background:white; height:auto; transform: scaleY(0); transform-origin: top left; width: 100%; }.dd-c ul { margin:0; padding:0; list-style-type: none; }.dd-c li { margin-botom:5px; word-break: keep-all; white-space:nowrap; display:block; position:relative; } a { display:block; position:relative; text-decoration: none; padding:5px; background:white; color:#C63D0F; } a:before { z-index:0; content:""; position:absolute; display:block; height:100%; width:100%; transform-origin:top left; background:#C63D0F; top:0; left:0; transform: scaleX(0); -webkit-transform: scaleX(0); } a span { display:block; position:relative; } a:hover:before { transform:scaleX(1); -webkit-transform:scaleX(1); } a:hover span { color:white; }
