Subject: [html-formfu] default style for options in a radiogroup
Message-ID: <53D66709.80403@united-domains.de>

Hi,

I am currently trying to set the (bootstrap) style for the options in a 
Radiogroup but having trouble adding an attribute class to the <span> 
tag for each option.

I would like the form output to look like this:

<form action="" method="post">
     <fieldset>
         <legend>sex</legend>
         <span>
             <span class="radio">
                 <input name="sex" type="radio" value="m" />
                 <label>Male</label>
             </span>
             <span class="radio">
                 <input name="sex" type="radio" value="f" />
                 <label>Female</label>
             </span>
             <span class="radio">
                 <input name="sex" type="radio" value="a" />
                 <label>Alien</label>
             </span>
         </span>
     </fieldset>
     <div>
         <input name="submit" type="submit" value="Submit" />
     </div>
</form>

I know it is possible to manually set an option container attribute as 
follows:

elements:
   - type: Radiogroup
     name: sex
     label: sex
     options:
       - [ 'm', 'Male' ]
       - [ 'f', 'Female' ]
       - value: a
         label: Alien
         container_attributes: <------------- here
           class: radio

however I would like this attribute to be applied to all options 
automatically since I am actually retrieving the options dynamically 
from the database rather than setting them manually in the form config. 
I tried fiddling with the layout in the default_args hash but all I 
could manage to change were the outer elements of the Radiogroup rather 
than the inner <span> which wrap around the options themselves.

Any assistance with this would be greatly appreciated.

Stuart.
