Menu
Description
The Menu control is used to give the user a choice what action to take next. Each item can have an optional image, some text and an arrow.
You supply it with a list of items, and it will create one choice for each item. When the menu is first displayed, you need to recalulate the size of the scrolling area by doing controlname.refresh().
To add a Menu to your app, choose the Menu icon in the Toolbar. Use the Property Editor to set the properties.
