Question about a code

I made this code for a Menu but when its pressed for a second time or the application is opened again the Menu List gets replicated, I like to show the menu Once, when the button get pressed Thank YouQuestion2

Instead of the add items to list block, use this block:
set ...Elements to make a list('Pepsi', 'Cola', etc.)

Use the blue button to add sockets.
