@Md_Jakir_Hossain I just want to add that your question is very broad. If you have a working example of what you have made so far, and have questions on a specific problem you are having, then you might get more help from the community. Nobody else but you can envision how you want your app to look and function.
@JackVaughan I would only add that it is possible to get admin and user functionality in the same app, but it’s very use case specific. Usually I like to add either an admin tab in the menu, or add an admin button or list in another tab. Depending on the situation, you can use a combination of per user data, visibility or relations to control if a user can see an admin section of the app.
