You can use toggleClass()
$(".top-bar").toggleClass("expanded");
题
function NavMenu() {
$(function() {
$(".toggle-topbar").click(function() {
$(".top-bar").addClass("expanded");
});
});
}
This function allows a Menu Button to expand a drop down for when running on a mobile/tablet device, ive so far got it this far, which expands the drop down, however how do i go about removing the class when i then click the option again?
Many Thanks
