[Zope] RE: How to prime a selection?

[RC Compaan]

Hi Jean

The value for a selection list can be any zope object that returns a list
eg. MyDocClass can have a property "Format" with a value "FormatList", where
FormatList is a dtml-method that returns a list.

Practically:
1.Go to the property sheet for your new class and add the property Format
with value FormatList.
2.Go to the Folder where you want to add an instance of your ZClass and
create add a property "docformats" of type "lines" and enter the initial
formats.
3.In the Folder where you want to add your instance, create a dtml-method
called "FormatList" that will return the list, containing:
	<dtml-return docformats>

Hope this helps.
