I am using Bootstrap v2.3.2 and jQuery Datepicker v1.10.0,
On a modal I am trying to make use of the datepicker and it is appearing behind the modal on Firefox and
As @Matt answered, apply z-index higher than modal’s z-index, suppose modal has the below z-index:
z-index
modal
modal.fade { z-index: 10000000 !important; }
Then apply z-index more than modal for datepicker class:
datepicker
.datepicker {z-index: 20000000 !important}
