I am using select library http://github.hubspot.com/select/ and noUiSlider https://refreshless.com/nouislider/. The problem I am facing is shown in the below picture
I have changed the options of "select" with the default style of "select-theme-default.css" and slider is created with the help of "noUislider.js".Slider is in higher z index than options and I want to change that. I tried changing the z-index of ".select-option" class to 5 and tried changing the class of ".noUi-connect" to 2. But it is not working. When I inspect the ".noUi-connect" and remove the z-index property completely it is working to some extent.
Try changing the css (Replacing the below css)
.select.select-theme-default {
-webkit-user-select: none;
-moz-user-select: none;
-ms-user-select: none;
-o-user-select: none;
user-select: none;
position: relative;
z-index: 99;
}
or you can override it
position: relative; z-index: 99;
is newly added here
