pop up widget change the background object when using it from mobile

[admin]

Try this CSS. It will make the value select smaller so it pops below the slider not above.

Code:

.control-vselect .popover-content {
  padding: 3px;
}
.control-vselect li {
  width: 50%;
  float: left;
}
.control-vselect li .a {
  margin: 3px !important;
}
