[Zope3-dev] RFP: menu item ordering

[Phillip J. Eby]

Perhaps it would help if there were some specific use cases being 
addressed.  Steve's old proposal addresses the use cases "it would be nice 
for menu items to be grouped by category", and "it would be nice to be able 
to order the categories".  Priorities, on the other hand, sound like a 
kludge to bump things up or down and an ongoing source of annoyance.

If the intent is to be able to require that an item appear before some 
other item, or after another, then item constraints might be the way to 
go.  If the intent is to allow someone precise control over total ordering, 
then a different tool is needed.  Is order dynamic, per object, per menu, 
or is there some total ordering of menu items in the abstract?

At this point, the goals are too vague to be able to pick a "best" approach.
