I want to change the default category menu for Prestashop on the left to work as follow:
1. If it is a category with NO sub category it will be shown as normal
2. When it is a category WITH Sub Category, the main category cannot be clicked, with mouse over of the main category, the sub-categories will slide open and they can be clicked.
3. Must have .css file so I can edit the look as I want it.
This must work with Prestashop 1.4.7.x and must install like a module.
