[Zope] How do you get custom made portal tabs to highlight

[David Pratt]

Hi Julian. The actions tool allows you to group actions. CMF on its own 
has nothing called portal tabs. This is Plone talk I believe. If you are 
developing in CMF which I am assuming, you are speaking of actions. Any 
object type can provide actions. In any case, it boils down to writing a 
script or two and including a conditional statement in your template to 
provide a class that you can style with your css.

Your python script(s) must:

1) Gather the actions you are interested in evaluating
2) Obtain the current URL and determine whether it matches an action 
from the actions you wish to evaluate (whether it is a part of the path 
or name). You will note that all actions have ids and a URL so this 
helps with this comparison.

Once you have some logic that correctly isolates the correct action 
based on the current URL, write a zpt condition in your template(s) to 
provide a class attribute in your html that you can style. It is common 
to give this attribute a name such as 'selected' for a horizontal or 
vertical menu for semantic purposes.

You should examine the api for the actions tool. The main_template in 
CMF groups object actions, folder actions, workflow actions etc as an 
example.  Hope this helps.

Regards,
David
