Admin Custom Controllers

[urfan.alimov]

Hello,

I am trying to add custom controllers to admin.

Though this is not my exact scenario i would like to acieve following:

I have certain admin users that can modify some fields of product entity. Lets say default sku price, currency and a couple more.

1) I will add a new module and section to admin.

2) I will not show all the fields/tabs to users. Only fields that users can modify.

3) Users will have a category restriction, i.e. user X can modify only products from category Y. ( i will extend adminuser entity)
List Grid will show products only with category that user is logged in.

4) I want to achieve this sceanario with custom controllers and using html templates of open admin. I want minumum html/thymeleaf coding.
I will add custom templates but include templates that are already in openadmin project. All i will do is CRUD.

I this something possible?

Thanks & Regards,
