A different side menu for the Homepage

Hello:

I just bought the template and installed it.

I’d like you to tell me how I can change the menu for the main page and how it’s different from the rest.
I want to have a home page open for all users (with news, information, etc.) and the rest that is only accessible to registered users.

The problem I see is that the left side menu is the same for all pages.
Is there any way to create a menu just for the homepage?

Thanks
