so i am attempting to make a tower defense game as my first ever go with clickteam fusion. I thought it would be better to go without tutorials, but since i am very very stupid, this doesnt seem to be a good option. Anyways, in most tower defense games, you can click a button to bring up a tower menu. then you can drag and drop the tower you want from the menu onto the map. An example of this is in bloons TD, and is shown in this handy little gif i attatched.

So i want to recreate a system simmilar to this, with the only difference of clicking a button and getting the menu to appear. also, is there a way to apply animations to this? for this specifically, i think it would look better if the menu slid in from the right, but its not exactly super important, but would be cool. Thanks!

edit: the gif didnt work
