[Krang-devel] Proposed change to building "Add Element" dropdown method

[Eric F. <ef...@pl...>]

As the element library I'm working on grows, it would be convenient to 
be able to better organize the elements that appear in the "Add Element" 
dropdown. What I would like to do is arrange them in optgroups.

This currently isn't supported, but with a change to 
Krang::CGI::ElementEditor it could be.

Currently, order_of_available_children returns an array of element 
names. To add optgroup support, we can have that method optionally 
return an array of hashrefs, structured like so:

         {
             optgroup => 'Meta Tags',
             elements => [qw(
                 meta_description
                 meta_keywords
                 meta_title
             )],
         },

In  Krang::CGI::ElementEditor's element_edit, we test the first element 
of the returned array, and if it is a hashref, we build the menu to 
include optgroups, otherwise, we do what we've been doing in the past.

Attached is a screenshot of a sample optgrouped menu.

Before checking this in, I just wanted to check with the group. 
Questions, comments?
