The ListBoxMulti control in IWML provides a scrollable list of options where users can select multiple items at once.

 

Unlike ListBox, which supports only single selection, ListBoxMulti is designed specifically for multi-selection behavior and avoids interface inconsistencies that could arise if selection mode changed dynamically.

 

Use Ctrl or Shift keys while clicking to select multiple items.

 

Syntax

 

ListBoxMulti[:Name]

 Items:

   ...

 ]

 

•Name — optional identifier to access the control in code.

•Items — list of selectable entries.

 

Properties

 

•AutoHeight — determines the height behavior:

▪-1: use explicit Height

▪0: auto-size to match item count

▪>1: fixed row count

•Sort — sorting method for entries (asc, desc, none)

•Values — optional values mapped to items

•Selection (JavaScript) — accessible via .Selected, returns an array of selected items
