For this you need to modify the js code .
Pls modify fie js/main.js line no:741-761 to
$('.home #campaign-header i').on('click', function (e) {
var content = $('#header-campaign');
if (content.is(":hidden")) {
$(this).addClass('open');
content.slideDown(300);
} else {
Cookies.set('mo_campaign_header', 'true', { expires: 7 }); // expires in 7 days
$(this).removeClass('open');
content.slideUp(300);
}
});
if (Cookies.get('mo_campaign_header') !== undefined) {
$('.home #campaign-header i').removeClass('open');
$('.home #header-campaign').slideUp(300);
}
else {
$('.home #campaign-header i').addClass('open');
$('.home #header-campaign').slideDown(300);
}
After modifying the code pls clear the cache and check .
