Hi ColinM,
Thank you for the comprehensive explanatory answer on limiting categories and the use of rights for this purpose. I think this works, but I'm interested in sorting the categories in the drop-down menu.
- On my first question above - sorting the categories alphabetically, as in the old version 1.9.2.11

- On my second question above - Category display type: cascading dropdowns. For example, categories have the following tree structure:
cat1
-cat1a
--cat1a1
---xxx
----xxx
cat2
-cat2a
--cat2a1
---xxx
----xxx
cat3
-cat3a
--cat3a1
---xxx
----xxx
xxx
Where cat1, cat2, cat3 are level1; cat1a, cat2a, cat3a are level2; cat1a1, cat2a1, cat3a1 are level3
One screenshot for such choice, but from another component:
