How to tile 1st gen child sub categories horizontally instead of ?the default? vertic

As you can see in the image,

this is how vBulletin 5 default style handles the following channel layout :
Parent category " no post " nested -of course- under [forum] ---- > 1st generation child category "no post i.e acting as a 2nd category under the parent category"
------ > 2nd generation child, a CHANNEL this time " i.e where user may post"
By default, vBulletin 5 default theme will implement the following -sometimes undesirable- formatting:
It will tile VERTICALLY aaaalll the 1st generation child categories !!
While in forums that may have relatively a bit too many 1st GENERATION CHILD CATEGORIES nested under a bit too many PARENT CATEGORIES; the result is an un appealing loooooong page that is stacked up sooo sooo vertically in a very un professional way !!
This certainly calls for a direct to the point functionality that gives users the choice of TILE VERTICALLY or otherwise TILE HORIZONTALLY
If we didn’t miss something , this function doesn't yet seem to be available in admincp
So meanwhile until the authorized vBulletin geeks in the vBulletin team will consider adding this functionality !.
We are left again soliciting any ideas , specifically codes for css_additional .css
Or a hook modification ?
S.O.S
