Question

I have found a tutorial on some dropdown menu using jquery. It works fine but I want to adjust it just a little. Instead of hiding the menu using hovering, I want to have the same button that showed the menu, to hide it when it is being pressed again. So the same button has to both hide and show the dropdown menu.
The script that im using:

    $(document).ready(function () {

        $("ul.subnav").parent().append("<span></span>"); //Only shows drop down trigger when js is enabled - Adds empty span tag after ul.subnav

        $("ul.topnav li span").click(function () { //When trigger is clicked...

            //Following events are applied to the subnav itself (moving subnav up and down)
            $(this).parent().find("ul.subnav").slideDown('fast').show(); //Drop down the subnav on click

            $(this).parent().hover(function () {
            }, function () {
                $(this).parent().find("ul.subnav").slideUp('slow'); //When the mouse hovers out of the subnav, move it back up
            });

            //Following events are applied to the trigger (Hover events for the trigger)
        }).hover(function () {
            $(this).addClass("subhover"); //On hover over, add class "subhover"
        }, function () {    //On Hover Out
            $(this).removeClass("subhover"); //On hover out, remove class "subhover"
        });

    });

Use jQuery’s .toggle() http://api.jquery.com/toggle/

$("#yourbutton").click(function() {
    $("#yourmenu").toggle();
});
