Advanced search child categories

Hi,
I've started working with the advanced search module and I am wondering if I am missing something..
I would like to display only main categories.
It would seem you could do this under the "Child categories level" selection but there is no option for choosing "none" or "0". It starts from 1.
Am I missing something? I can see this is done on the demo site as well.

Hello Nava,

We only display the parent categories there. When you click on a category, then child categories will be shown.

Hope that this is useful.
Sincerely, Giang

That is what I would like to do.. Or just to display the parent categories and no children at all.. Is that possible?

Hello Nava,

Then it should work like you want. If not, please submit a new ticket to EShop category to send me the your site information so I can help you to check.

Sincerely, Giang
