What is it/what does it do?
When you hover over a category, if the category has children it pops out showing the next layer of categories.
It does this for multiple category layers.
All links are shown in the source code as pure html links which can have SEO benefits because your deeper categories are shown on page one.
The user also benefits because it is only one click to a category.
Queries and efficiency
This menu system only uses one query but that query is a full categories scan. There is an in-built system of caching which stores the categories array as a serialized file.
The cache is very simplistic in as much as it does not have a "lifetime" however you can reset/rebuild the cache at any time via the admin settings.
Is it easy to install?
Very easy, only one piece of code needs to be added above the </head> to the catalog files (adding a stylesheet).
One small change is made to includes/column_left.php.
