We can offer you two ready-to-use solution:
The add-on "Accordion menu" displays the category menu in drop-down in a side block on the page you want.
Or the CS-Cart modification "Mega Drop Down Menu" that allows to organize products due to groups of options, insert pictures in the menu or add sub-levels in the menu panel, that will be shown on hover.
But, as I understand, none of these solutions will meet your demands fully. We can change any of these add-ons due to your requirements and it will be cheaper than to create the modification from scratch. Contact us.
