Hi,
the next thing I have to do is to generate a dropdown (selectbox) with
optgroups.
In my example I want to group Locations according to their countries.
At the moment I just search for the locations with find('list) and set
it for the view so the select-box will be populated automatically by
Cake.
The problem I have now is that I have no idea how to group my
locations with their corresponding countries. All locations have a
field "country_id" where the country can be accessed.
I assume I have to do sth with a foreach loop to populate the select
box correct, but I would appreciate if someone could give me an
example on how to do things like that!
Thanks in advance!
