Hi I am looking for a solution to expand and collapse the categories menu the same way as the cart expands which means that the expand/collapse status is stored in the session and the status is kept over multiple page requests. The dynamic categories menu now collapses when the user requests another page (e.g. about us) than a product page. This is in my opinion not what a user expects since he expands the menu explicitly before. Does anyone has an idea how to implement this behaviour? Is there an easy way to store the menu status as an variable over requests or do I really need to impement an AJAX solution like the one used in the cart?
