Hi,
I am looking to implement Expanding/Collapsing Products Menu implemented on MEDICAL-TOOLS.COM/SHOP
http://medical-tools.com/shop/manicure-instruments/.
Its almost like "Tree View" of fancy menus except that sub-categories are shown by clicking on the Parent Category and not just small arrow/triangle which expands the menu and shows sub-menus.
I have also found an add-on by BSC ENGINEERING
https://www.bcsengineering.com/store/download.php?id=60e70932247c45223d1ff97fbfd39bac but their module doesn't support 4.5.X so far.
I will be thankful for any guidance and advise.
