Noob Question about Navigating from Screen to Screen

So in my game a character in the open world clicks on something and a screen pops up with information and navigation buttons to give them other info, inventory, skills, crafting etc. So I set it up when the player clicks on the object in the open world it opens a new Level. Once on the main screen of the new level do I have to make a new level for each button they can click on that opens another screen or is there a way to keep things in the same level?
