HTML标题菜单下拉菜单无法单击

好的。我有一个用HTML设计的标题-但是，每次我将鼠标悬停在产品上，然后单击ANY子菜单时，我都无法（它们在被点击之前便消失了）。

可以在http://www.bwl-ny.com上看到一个实时示例。

有什么建议？

Custom.js

$(document).ready(function() {

//INITIALIZES PRETTYPHOTO PLUGIN

    $("a[rel^='prettyPhoto']").prettyPhoto({theme:'light_square'}); //choose between different styles / dark_rounded / light_rounded / dark_square / light_square / facebook /

//INITIALIZES TWITTER FEED PLUGIN

    $('.twitter-feed').tweet({
        username: 'ABrighterWorld',  //just enter your twitter username
        join_text: 'auto',
        avatar_size: null,
        count: 2, //number of tweets showing
        auto_join_text_default: '',
        loading_text: 'loading latest tweets...' //text displayed while loading tweets
    });

// FLICKR PLUGIN

    $('#flickr-images').append('<ul></ul>');

            animation:     {opacity:'show',height:'show'},     // an object equivalent to first parameter of jQuery’s .animate() method 
            speed:         'fast',           // speed of the animation. Equivalent to second parameter of jQuery’s .animate() method 
            autoArrows:    false,               // if true, arrow mark-up generated automatically = cleaner source code at expense of initialisation performance
