Detailed Description

This is a visible component that allows to place a list of text elements in your Form to display. The list can be set using the ElementsFromString(String) property or using the Elements(YailList) block in the blocks editor.

Warning: This component will not work correctly on Screens that are scrollable if its Height(int) is set to Fill Parent.

@internaldoc TODO(hal): Think about generalizing this to include more than text.
