The current menu listing that you see if just a simple selection of all the categories and the items in those categories. If you want this art menu option to contain only certain categories then you will need to alter the recordset that is in this this part of the menu. You will need to modify to filter on the categories you would like to display.
There are other ways this can be accomplished but they are all a bit more advanced and will require some custom coding and db administration to incorporate into your admin area. For example if you added another column to the categories table to indicate if it were art or not then you would need to update the admin pages to be able to record this value and store in the table. You would then need to go and alter the recordset code on the that part of the menu to filter where the category is art and you would need to modify the other one to exclude these categories.
