Help:Property change type
From COST Action FP0804: FORSYS
To change the property type, you simply must edit the property page and add a property like:
[[Has type::number]]
See http://semantic-mediawiki.org/wiki/Help:Properties_and_types#Datatypes_for_properties for a list of property types.
Page type
If changing to type Page, and you want a set of values available for a form, one must create a page for each value.
Example:
Property:Has decision making dimension
When used in form, {{{field|Has decision making dimension|input type=listbox|values from category=Decision making dimension|size=3}}}
Gets values from a few pages which have been tagged with [[Category:Decision making dimension]]
