I made a .gui file. I followed GUI tutorial.
The file have some font, text node, image node, gui script and layers.
And then, I tried to put the gui on the game scene.
But, I cannot find any menu to insert the gui on the game scene.
Drag&drop didn’t activated when I drag the gui file on the collection panel.
When I execute my game, main.collection is executed. The collection have some sub collections.
But, I can’t add any gui file to the collection.
How can I put the gui on the screen.
The GUI scene needs to be added to a gameobject that reside in one of your collections.
Open your gameobject file (or select the gameobject in your collection), then right click on the gameobject and select “Add component from file” where you should be able to add your GUI scene.
It worked!
Thank you for your quick response. sven.
Anyway in collection scene, I can not see the added gui component.
I can only see the gui at execution time. It’s very inconvenient.
Yay! 
Yes I would agree that’s inconvenient. 
We have plans for GUIs being visible in the editor, when viewing collections, but I don’t know if it will land in the current editor or editor2.
