Today I want to talk about the module called Hierarchical Category Filter. Its purpose is to get quick access to certain categories of website. But all in good time… First of all I would like to note that I have not found a more simple solution to display a list of categories, and at the same time easily customizable. With the help of it you can filter sub-categories, which are parent elements, and allocate the necessary material.  Main benefits: Design dependent list of categories. Allows set own label for each . The ability to assign double units in the same category. Loading the menu items via AJAX (if available). module
