My wild guess is that you should override addMultiOptions in a custom
select element so that you can add the class attribs.

From my googling I see that this has been asked, and there's no really
easy
answer, and none of the few answers I found work for my case.
Basically, you have a label, a value and a category signified by the css
class. I want the output to be something like
<option label="apple" class="fruit" value="1">apple</option>
<option label="spinach" class="vegetable" value="w">spinach</option>
<option label="salmon" class="fish" value="1">salmon</option>
And yes, I know there are option groups for organizing OPTION elements
into
a hierarchy, but I have my reasons for not wanting to go there.
This will all come from a database. In high-level terms, how would you
suggest approaching this? What classes/methods would you look into
overriding?
The purpose is to do fancy tricks using jQuery -- I need to detect the
"category" on the change event. I can think of ways of hacking around
this,
e.g., load a JSON data structure that maps ids to categories and refer to
that as needed. But... any other ideas?
Thanks Bart.
I noticed that $helper is a public property of Zend_Form_Element_Select, so
rather than extending it, I have started working on a custom view helper
instead, whose method signature is the same as that of formSelect in
Zend_View_Helper_FormSelect.
But the $options array that I am going to pass the Zend_Form_Element_Select
constructor won't be like array( 1=> apple, 2 => spinach ), but rather
array( array(value=>1,label=>spinach, class=>vegetable ), ... )
Any thoughts about this approach? I know that it's kind of crude to
deliberately abuse Zend_Form_Element_Select's constructor and then give it a
custom view helper to make up for it, but it looks like it's gonna work.
Indeed it sounds like it's going to work and I do not see the crude
aspect. If the constructor can be used this way it is the strength of
the architecture that makes this possible. I looked at the issue in the
tracker and that doesn't sound bad either, although I wonder how it
would perform with a lot of options.
