Product Categories/Blog Templates

i have been trying to figure a way to create top level product categories for marketpress so when a sub user adds a product they would have to select one of the existing categories or they could create a sub-category under of the the top level categories i created. using the new blogs template plugin i was able to accomplish this.. but..

is there a way to remove the option "parent category" from the drop down so they have no choice but to select one of the existing or create a sub-category.

also how can i remove the link to the product category page... OR remove "none" from parent selection when creating a category and remove the ability to delete top level categories?

thanks in advance! :slight_smile:
