Select-Shuttle question

[Jim Steil]

First of all, I hope this is the right place to ask questions specific to the SelectShuttle widget.  If not, please direct me to where I should post my question, and sorry for the noise.  If so, please read on.

I have been using the SelectShuttle widget successfully for some time now and am very happy that such a widget exists.  It makes things really easy to setup.  My problem is that I have a need that SelectShuttle doesn't seem to support.  I'll do my best to describe what I'm looking for...

*  I have a contacts database and want to assign contacts to certain categories. 
*  Users are restricted as to which categories that can assign/unassign a contact. 

I would like to be able to disable the categories in the list that the logged in user does not have access to.  The category should still show up in the 'selected' list, but the user should not be able to remove it from that list.

In the example below, some users should not be able to add/remove the 'Contact Price Sheet' category, but if it is on a contact, all users should be able to see it.



I played with this a bit and set the disabled option on the select field when populating the widget as follows:

        options.append((ctg.id, '%s' % (ctg.name), dict(disabled="disabled")))

This works, disabling the row in the select field, but double clicking on a disabled row just re-enables all the rows that were disabled.  So, it appears as though it is inheriting the disable feature from some underlying widget, but does not make an attempt to honor a disabled row. 

I have not dug into the Select-Shuttle code (I'm not real good with javascript) but was wondering if this would be considered as an enhancement.  Or, if I'm doing something incorrectly and this capability is supported, could you point me to some doc or examples on how to use it?

Thanks again, I love the widget, just trying to push the envelop a bit...
