Greetings! This is an exceptional component I’m already making use of 
.
Is it conceivable to append additional settings for the selection of certain categories in the sidebar? At present, the administrator does not have (or at least, I have not found such an option in the admin settings) the ability to specify which categories should be displayed in the sidebar, and which should not.
Ps,
Perchance my next query doesn’t pertain to this particular facet of the subject, necessitating the drafting of an autonomous post, yet I find myself confronted with the ensuing conundrum:
Aside from categories, is it feasible to incorporate into the sidebar a similar dropdown list of subcategories with an arrow? 
.
For instance.
CATEGORIES (*The designation of the segment within the lateral console.)
-- 
Category 1 (*Parental)
- Subcategory 1
- Subcategory 2
-- Category 1 (*Parental)
- Subcategory 1
- Subcategory 2
