background: #efefef;
box-shadow: 0px 4px 4px rgba(0, 0, 0, 0.25);

export default Slider

here is the code

CodePudding user response：

If two positioned elements overlap without a z-index specified, the element positioned last in the HTML code will be shown on top, and from the looks of your code, your slider has a higher stack order. Source

To fix this, try giving the .dropdown a higher z-index so it goes on top of the slider.

Fix

.dropdown {
  z-index: 100;
}

Or

It may be better if you give the menu itself the z-index property so the entire menu overlaps the slider and not the dropdown alone.

.menu-area {
  display: inline-block;
  text-align: center;
  position: absolute;
  left: 50%;
  transform: translate(-50%);
  z-index: 100;
}
