Active pseudo class state with active CSS class absorbs onclick event

I adapted the example found here to be a bit more like the “real” menu in which it should crash on user clicks.

I like the fact that all the visual aspects of the menu are considered in css, with javascript entering the game only to handle the action required when the user selects a parameter. I believe this is the most suitable approach for my specific application.

However, I find the onclick event that I assign for each link is removed (or ignored) when the menu is removed.

I publish 2 versions that work in the sense that when users select a parameter, the desired onclick event is fired, and the other one beautifully discards the menu and also swallows the onclick event. I get a solution that combines 2 results into a work menu, which will also satisfy the requirement to postpone itself after a click.

EDIT just noticed some additional code that I commented on (an earlier attempt before computing only the css solution. I called mouseleave without effect.

The only difference between the two versions is the addition of the CSS clause:

#menuwrapper ul:active{
    display:none;
}

A version that "works" but does not collapse the menu

   var display = document.getElementById("display");
   $(document).ready(function() {
     $('li.menu_clickable').click(function() {
       if (this.children.length === 1) {
         //$(this).trigger('mouseleave');
         display.innerHTML = 'you clicked ' + this.innerHTML;
       }
     });
   });
