The below code is working,
<style>
.PanelFloat {
position: fixed;
overflow: hidden;
z-index: 2400;
opacity: 0.70;
right: 30px;
top: 0px !important;
-webkit-transition: all 0.5s ease-in-out;
-moz-transition: all 0.5s ease-in-out;
-ms-transition: all 0.5s ease-in-out;
-o-transition: all 0.5s ease-in-out;
transition: all 0.5s ease-in-out;
}
</style>
<script>
//The below script will keep the panel float on normal state
$(function () {
$(document).on('scroll', function () {
//Multiplication value shall be changed based on user window
$('#MyFloatPanel').css('top', 4 * ($(window).scrollTop() / 5));
});
});
//To make the panel float over a bootstrap model which has z-index: 2300, so i specified custom value as 2400
$(document).on('click', '.btnSearchView', function () {
$('#MyFloatPanel').addClass('PanelFloat');
});
$(document).on('click', '.btnSearchClose', function () {
$('#MyFloatPanel').removeClass('PanelFloat');
});
</script>
<div class="col-lg-12 col-md-12">
