I seem to be facing an issue with the side navigation drop down menu. Below are the link and CSS code:
<nav id="nav">
<div class="menu-main_nav-container"><ul id="menu-main_nav" class="menu"><li id="menu-item-270" class="menu-item menu-item-type-post_type menu-item-object-page current-menu-item page_item page-item-6 current_page_item menu-item-270"><a href="http://449design.net/clientpages/gamiing/">Home</a></li>

</ul>
</li>
...
#nav ul.sub-menu li a:hover {color: #000;}
/*Second Level*/
#nav .sub-level {
background: #999;
}
/*Third Level if needed*/
#nav .sub-menu .sub-menu {
background: #09C;
}
It seems that there is an issue where parts of the drop-down menu disappear when hovered over or are difficult to use. I have been trying to find a solution for this problem without success.
