Do you mean that you want to make the main menu bar sticky on top in JA Biz template? As I can see that your site is using JA Magz now.
If yes, you can try with my workaround:
– Open file: templatesja_biztplsblockshead.php and add this block of code at the end of file:
<script src="http://stickyjs.com/jquery.sticky.js"></script>
<script>
jQuery(document).ready(function(){
jQuery("#t3-mainnav").sticky({topSpacing:0});
});
</script>
– Go to file: templatesja_bizcsscustom.css (create this file if it doesn’t exist) and add this css rule:
.sticky-wrapper.is-sticky .t3-mainnav.navbar.navbar-default {
width: 100%;
}
