How can I make the dropdown list overlay the outside card?

Question

I have a dropdown list inside the Google Material Design card. When clicking the button, the dropdown list would not overlay the card. I have tried to set the z-index to a larger value but it did not work.

Here is my jsfiddle code.

Answer 1

It's not show outside the card because it's parent have overflow:hidden property.

So, You need to add css for that :

.mdl-card {
      overflow: visible !important;
}

.status-card {
  min-height: 15% !important;
  display: block !important;
}
.mdl-card {
  overflow: visible !important;
}

.status-card > .mdl-card__supporting-text {
  margin-bottom:0px !important;
}

.status-card > .mdl-card__supporting-text > .mdl-cell--10-col {
  padding: 8% 0 8% 2%;
}

.status-card span,
color: black;
}

.status-card li:before,
content: '■';
padding-right: 0.5em;
font-size: 170%; /* or whatever */
}

.status-card ul,
max-height: 140px;
overflow-y: auto;
}

    <button id="test1" class="mdl-button mdl-js-button mdl-button--raised" style="margin-top: 8%"></button>
    <ul class="mdl-menu mdl-js-menu mdl-js-ripple-effect mdl-js-ripple-effect--ignore-events" for="test1">
      <li class="mdl-menu__item" style="color: #cd8daa;"><span>xyz</span></li>
      <li class="mdl-menu__item" style="color: #cd8daa;"><span>yue</span></li>
      <li class="mdl-menu__item" style="color: #cd8daa;"><span>24</span></li>
    </ul>                       
    <div class="mdl-cell mdl-cell--6-col" style="display: flex; flex-flow: row wrap;">
      <h6 title="">TEST</h6>                            
    </div>                                     
  </div>
</div>

Answer 2

Add overflow

.status-card {
    min-height: 15% !important;
    display: block !important;
    overflow:visible;
}

give this one id="status-card-1"

#status-card-1{
  z-index:20;
}

Here's the fiddle

The dropdown list doesn't overlay the card because ".mdl-card" has "overflow:hidden". You can override ".mdl-card" with value "overflow: inherit" or "overflow:visible"
