How do I configure the app menu?

Hi! I am having issues with my menu sheet. I looked at Glide examples and I still can’t figure out how to make my sheets appear in the main menu (LAYOUT) of my app. I want to make 3/4 of my excel sheets be 3/4 sections in my layout (because they have tons of info inside) and be able to edit the info inside each sheet to change the sections from there. But I cant figure out the basics. Please help !:slight_smile:
