Drop down list

Rails
#1

In my application I have 2 objects. An Item object and SubItem object.
What I would like to do is make a single drop down list that has all of
the Items in it, then if the item has a SubItem attached to it, then it
will be displayed directly underneath that Item with some sort of
indentation or marking to indicate that it is a SubItem. I don’t even
know where to begin looking for this type of problem. Any ideas?

It would be great if Tabnav (q.v.) could be adapted to use this!

Failing that, something that reads in a .yaml file that specifies the
menu :slight_smile:

Cool thanks. I didn’t think to do something like that. I was going more
of the standard <%= f.select(:item, Item.find(:all)) %> style drop down,
but this way could work too.
