How do I open a new layout?

Is there any way to open a layout inf front of other layout?

You mean inside the editor or overlap the layouts during the game?

Your screenshot don't seems related to the question, or perhaps I am not understanding well what are you asking for.

Well, its not a game, its a proggrame for store product and its gone open with wj. Lets say in a layout i have 2 buttons the first button navigate to product layout and the second button navigate to the price of products layout. Its possible to open this 2 layouts same time side by side?

Jerementor did a good video tutorial time ago about include one layout as HUD inside the normal game one.

You could use the same technique and eventually move the position of all elements of the two different layout to left and right side to put them as you want. You could use families to help you move all elements of one time of each layout.
