Arguments: item-list
Returns true if the items of item-list will be arranged into multiple columns when needed. This is done only when the items do not fit vertically into a single column. The column-width property determines the actual width of the columns.
The multi-column-p property may not be changed on an existing control, and must instead be specified with the inspector when designing a control (using a form) or with the :multi-column-p initarg of make-instance. (It can be changed using the inspector when designing a form but not for a running control, either in the IDE or in an application.)
multi-column-p is a property of the multi-item-list and
single-item-list classes.
