Qué hace

Constructs a new RM-Selector dropdown widget: an optional caption over a button that opens the workbench selector popup. SetList takes a map of keys to text (or {text, icon}) and an optional order, sorting by text otherwise; choosing a different entry fires OnValueChanged. It returns the registered but not yet acquired widget; addon:CreateConditionDropdown acquires it.

Argumentos

Ninguno.

Retornos
