Removing template categories

[eastcoast]

How do I remove categories from the drop down menu on the Design page. Even if I remove all the templates of a certain category and set up a plan without certain categories, all the categories appear in the drop down menu. This is confusing to customers.

In current version there is no way to manage template's categories through Sitebuilder panel. Yon can do it only directly on the server in Mysql database. For this you need to log into Mysql as administrator and work with 'sitebuilder3.template_category' table.
As I know such functionality as managing categories for templates is planned to release in future Sitebuilder versions.
