A stack field appears as a set of fields that remain aligned if you rearrange or reorder them. The stack can include any combination of fields.

A stack field is useful for laying out fields so that they stay aligned when you port the form to another environment. For more information about using stack fields to create portable forms, see the Programming Guide.

Fields in a stack field are arranged either vertically or horizontally in a one-dimensional array, depending on the setting of the Orientation property in the Property Inspector.

The ChildTopMargin, ChildBottomMargin, ChildLeftMargin, and ChildRightMargin properties let you specify margins for each child field of a stack field. The ChildGravity property determines the position of child fields in the stack field cells. You can use the Property Inspector to set these properties; you can also use the Gravity property of a stack field's children to control the placement of the children in the stack field cells.
