I would like to try to achieve the kind of categorization showed on the picture attached. The example shown is taken from another instance of WHMCS so I know it's possible.
It is a drop down menu that refreshes the page according to the given choice. For instance:
CAT 1 (containing some products)
CAT 2 ""
CAT 3 ""
Etc, where every time a category is chosen in the dropdown a X amount of products appear.
Furthermore it has 2 more sub categories right below the drop-down:
With something XYZ
Without something XYZ
Which also refresh the page showing its own set of products
I cannot seem to understand how to accomplish that, can anyone help me please?
