When a field or label needs more than one of the panel columns, set this to the number it should use, such as 2.
The responsive web IslandPanel will, by default, place a label in a column, then the related fields in the next column of a panel. Sometimes based on organization of the fields and labels, it can be useful to "stretch" a field (or fields) to occupy more than one column, particularly if it is a long field.
Default: 1
