Like Pane, this display element groups other display elements as a single logical element.

Unlike Pane, the Scroll Pane element has a predefined size and it displays a horizontal and/or vertical scrollbar if required.

Internal Modeling

To define the contents of the Scroll Pane, add one or more display elements. Typical modeling makes use of other container elements such as Row, Grid, and Table, although any display element, except View, can be used. 

It is very common to add an action sub-model that initializes elements in the scroll pane. Such an action would have no triggers (and thus be performed automatically when the scroll pane is activated) and would contain a reference to the scroll pane through which default values of fields are set.
