Ok, I've finally managed to make it work using the tips you game me, thank you.
But, as usuall, as soon as you fix one problem another appears... I'll try and see if we can fix it here before creating a new topic.
I've been reading around and it seems cocoonjs(with which I plan to export my game) doesn't support the button form control that construct 2 has, or the textbox for that matter. So the only option I am left with is list.
Is there any way I can make some normal buttons(I want to have a menu "start game", "options", etc.) with C2+cocoon so I don't have to resort to the dreadfull list option?
Basically this is how I've set it up at the moment(still have to position it and add background images, so ignore the way it looks for now) and I would like to keep it like this and preserve the functionality of the diff buttons, but in a way that works with cocoon.
