if (checkElement.is('.treeview-menu') && checkElement.is(':visible')) {
checkElement.slideUp(animationSpeed, function() {
checkElement.removeClass('menu-open');
});
checkElement.parent("li").removeClass("active");
}
//If the menu is not visible
else if ((checkElement.is('.treeview-menu')) && (!checkElement.is(':visible'))) {
//Get the parent menu
var parent = $this.parents('ul').first();
//Close all open menus within the parent
var ul = parent.find('ul:visible').slideUp(animationSpeed);
//Remove the menu-open class from the parent
ul.removeClass('menu-open');
//Get the parent li
var parent_li = $this.parent("li");
//Open the target menu and add the menu-open class
checkElement.slideDown(animationSpeed, function() {
//Add the class active to the parent li
checkElement.addClass('menu-open');
parent.find('li.active').removeClass('active');
parent_li.addClass('active');
