Probably some CSS issues that have to be worked out. What browser are you seeing these issues in?I am running the code downloaded from GitHub with v2.0.0 of Touch. Your demo works fine in the same Google browser. Running on Ubuntu.
I have taken your main.js as my class and I can display it fine and it works fine but no text ...
I can see the text in the html, for both the groups and the items, but nothing shows on screen. The click events all work too. No errors in the debug console.
I don't have a device to test on.
Any ideas ?
