It can only be bound to a select type (or subclass thereof), and inherits the configuration
from there as far as possible.
Available configuration options:
- int height: The height of the select box, applies only for multiselect enabled
boxes, the value is ignored in all other cases. Defaults to 6.
- string othertext: The text that is used to separate the main from the
other form element. They are usually displayed in the same line. The value is passed
through the standard schema localization chain.
The initialization event handler post-processes the maxlength setting.
Adds a (multi)select widget to the form, depending on the base type config.
Create a sortable list
Select automatically every object.
This is for using the widget only to sort, not to select what
has been sorted.
