  1. remove that line.

  2. resize the phone view.

  3. Add Scrollbar Handle.

  4. Add Scrollbar Handle

The UI of app inventor made with GWT you need to take look at appengine folder >>

UI is divided into small small parts so probably you need to explore more into appengine folder.

thanks, Parva nice to meet u.

Your welcome

Its so easy to make panels scrollable, no need to modify java files, just add the calc property to whatever you wanna make scrollable

Sample :

height: calc(1000px - 200px);
overflow: auto
