In cscart 3, latest version, my client was adding new categories. This was, like the cs cart 3 demo, showing as a dropdown select which he loved. After adding a new category however it changed and he hates this interface. It pops up a box with radio buttons instead of being a drop down to select a category to add to a product. Additionally on categories edit page in the admin, it no longer shows the expand all. This really makes him angry and it makes the time for him to add products and edit categories a lot longer, is there some code in cscart that controls which layout it is? Maybe depending on the number of categories? It changed on the old 2.0 cart too but we didn't get to fix it… on 3 he was so happy with it the new way and it changed “literally 3 seconds ago” and we can't get it back. What controls this is it an option?
I'll provide screenshots if desired but the differences are this:
On search page it uses pop up box instead of dropdown for selecting categories
On the product edit page the pop up box doesn't allow you to expand all categories at once the +/- button isn't on the top to allow this. It also doesn't show the categories expanded by default.
On the categoies page it doesn't allow you to expand all categories and doesn't show them all expanded by default.
Other pages to don't use the dropdown box which is much faster and overall less clicks and less loading time.
Anything you can do to help I appreciate. If you need screenshots i can do that too.
If I remember it used to chenge on the old v2 when a certain amount of cats etc were reached. try a search for category quantity list.
or category drop down

Ok thanks 
Did you ever get this issue resolved? I have the same problem. I don't like having to select the radio buttons. I prefer selecting from a drop down. I do have a lot more categories with the new website we are building using CS 3, so maybe that's the problem.
Thanks.
