[development] Form element wrapper IDs

[Martin Stadler]

Hi!

I stumbled upon the issue that there are no form element wrapper IDs  
for radios and checkboxes without the #title or #description  
attributes in D6 (http://drupal.org/node/215301). I need an ID to hide  
the label with CSS for accessability. I checked how this is in D7 and  
it seems to me that there are no wrapper IDs at all, only classes  
which are in the case of radios and checkboxes not unique (I know that  
classes are not supposed to be unique, that's why I want IDs):

<div class="form-item form-type-radios form-item-myformelem">
   <label>My Form Element </label>
   <div class="form-radios">
     <div class="form-item form-type-radio form-item-myformelem">
       <input type="radio" id="edit-myformelem-0" name="myformelem"  
value="0"  checked="checked"  class="form-radio" />
       <label class="option" for="edit-myformelem-0">Option 1 </label>
     </div>
     <div class="form-item form-type-radio form-item-myformelem">
       <input type="radio" id="edit-myformelem-1" name="myformelem"  
value="1"   class="form-radio" />
       <label class="option" for="edit-myformelem-1">Option 2 </label>
     </div>
   </div>
</div>

In modern browsers this may be ok but in IE6 I can't access the  
wrapper div nor the top label directly.

If #title is omitted in the PHP form api code then we get

<div class="form-radios">
   <div class="form-item form-type-radio form-item-myformelem2">
     <input type="radio" id="edit-myformelem2-0" name="myformelem2"  
value="0"  checked="checked"  class="form-radio" />
     <label class="option" for="edit-myformelem2-0">Option 1 </label>
   </div>
   <div class="form-item form-type-radio form-item-myformelem2">
     <input type="radio" id="edit-myformelem2-1" name="myformelem2"  
value="1"   class="form-radio" />
     <label class="option" for="edit-myformelem2-1">Option 2 </label>
   </div>
</div>

How can I style this individual wrapper now? I may have multiple  
radios in my form.

Actually the problem is the same in D6 and D7. In D6 we have wrapper  
IDs but not for radios and checkboxes and in D7 we have kind of unique  
classes for the wrappers but these are not unique for radios and  
checkboxes. Why were the wrapper IDs removed in D7? Pseudo-unique  
classes seem strange to me. How can we have a unique accessor for  
wrappers for radios and checkboxes? Can we add the wrapper IDs for  
them in D6? Why were these wrapper IDs unset in D6?
