Our website [url removed, login to view] is run on Zen Cart. In an effort to increase sales, we are looking to make our products better organized in order to make it easier to navigate. We want every category to have sub-category for each teams. However, we have a problem because it is not easy to do this from the Add Product feature, to put the products into multiple categories. At the moment, we have a mod in the "New Product" page within the admin which allows us to assign a product to multiple categories. However, this is simply listed in alphabetical order which is quite cumbersome. For example the categories are listed as: Arsenal Brazil Brazil Chelsea Man Utd Man Utd etc. As you can see, there are duplicates. We want it to change so that it lists categories and sub-categories in a tree like format as follows: English Teams Arsenal Chelsea Liverpool Italian Teams Milan Juventus Udinese New Jerseys Arsenal Chelsea Liverpool We need someone who can apply this modification, allowing us to assign a new product to multiple categories. WE WILL NOT CONSIDER BIDS, UNLESS YOU PMB US AND EXPLAIN TO US HOW YOU WILL ACCOMPLISH THE TASK, SO WE ARE CONFIDENT YOU UNDERSTAND OUR REQUIREMENTS.
