D13 Alpha Five v11 Dialog Control Scrollable Repeating Section

If you have a Repeating Section in a Dialog, you can put buttons below it to add or remove rows from the Repeating Section. When you add or remove rows, all of the controls on the Dialog that are below the Repeating Section will move up and down as the size of the Repeating Section changes. You might prefer to put the Repeating Section in a fixed-size, scrollable container. When you scroll this container, however, you want the titles for each column in the Repeating Section to remain fixed. This video shows how this is easily done.
