Hide first level category and instead display only secong level
I have only 2 categories of level 1 and more of categories in level 2 and 3.
Therefore I would like to ask if it is possible to hide level 1 categories and instead show level 2 as level 1 with some formatting in css.
For example:
I have
A
-b
--c
--c2
I want to show
B
-c
-c2
