CSS - what should I do to solve this? - css

Question

I use the chosen library and my dropdown appear like this, how can I solve this.
Thanks.
Like you can see on the picture the list of values appear under another element instead of being at the first plan, so the list of values is invisible.
What should I change in the CSS to workaround that.
Here is the CSS :

Answer 1

Elements showing on top or below each other can be managed in css with z-index property. You may apply -1 for the element that comes on the top.

Answer 2

Place dropdown inside a div with class 'chosen-upward'
<div class="chosen-upward">
your dropdown with class 'chosen-select'
</div>
Add to style
.chosen-upward.chosen-drop{top:inherit!important; bottom:33px!important;border-bottom-right-radius:0px!important;border-bottom-left-radius:0px!important;border-top-right-radius:4px;border-top-left-radius:4px;box-shadow:none!important;}
This will make the dropdown appear above the select control.
