Distributing slack to avoid scroll bars
To avoid scroll bars in panels, you can define the order (priority) in which panels in a panel holder can access the panel holder's available white space. This white space is called slack, and the priority by which it is allocated is called slack distribution order.
Slack distribution order enables you to allocate slack to the panels that need it most. For example, you might have a panel holder with three panels, one of which contains a table that you want users to scan easily with little or no scrolling. You can give this panel the highest slack distribution order so that it will have first access to the available white space in the panel holder.
Slack distribution order applies only to panels in collapsible and splitter panel holders; it does not apply to panels in tabbed and accordion panel holders because they display only one panel at a time.
Slack is available only on forms displayed in a browser.
The slack distribution order value is a positive number between zero and 100. The higher the number, the lower the priority for allocation of slack. A value of zero (the default) is the highest slack distribution order.

The panel with the highest priority gets the slack, up to the maximum size set in the panel's properties (see the above figure). A panel with a dynamic maximum size gets slack until all of its contents fit in the panel without a scroll bar appearing. Any remaining slack is distributed to the next visible panel in the slack distribution order.
Panels in a panel holder with the same slack order have slack allocated or denied in a round-robin fashion until all the panels reach their maximum size.
