[SOLVED] FLEXIcontent Categories module issue

Hi!
I have created several categories with such hierarchy:

Cat1
--Subcat1
--Subcat2
Cat2
--Subcat1
--Subcat2



Now I want to display this categories with module.
But I can't do it, because I must set parent category.



So, how to displays all categories from the root?

May be I need to create root category before?
In this case I'll get too long urls with excess prefix like /root_category_name/cat1/subcat1/item

Thanks.

you need root cat by you can remove your root cat in url by using flexiroute plugin

Thanks Micker.
So, now I need to create root category.
Tell me please, how I can move all categories created before to new root category?
Thanks.

you need to move it by edit each category. Sorry no batch action
