Hello All, Is it possible to create Similar Functionality as of User Roles (For Read Write Access), outside of studio-pro, on WebPage. Example: Each Student Group (Entity-1) Can have multiple Students (Entity-2 Inheriting From Account), Each Group of Students can Access (Read/Write) some Books (Entity-3). On the Webpage, I have created a student Group “Science”, assigned students to Science Group and assigned some Books to Science Group. Now I want to Control the Read/Write Access of Input Widgets/Pages using this Group (Similar to User-Roles). That is Only Students Belonging to Science Group can Read/Write Books assigned to this group. What expressions/xpath should I use and how , considering Student will loggin on Mendix Page.
