Hi,
I have resolved the issue by using given below js code.
<script>
jQuery( document ).ready(function() {
jQuery('.swift-search-link').click(function() {
jQuery('.sf-super-search').show();
});
jQuery('.super-search-close').click(function() {
jQuery('.sf-super-search').hide();
});
jQuery(window).scroll(function() {
var height = jQuery(document).scrollTop();
if(height > 500 )
jQuery('.sf-super-search').hide();
});
});
</script>
Thanks
