ruby on rails - simple_form custom wrapper with a plain radio button -

i trying make custom wrapper hybrid form this:

the idea here there radio buttons enable either date picker, occurrences or indefinite. have these manually created , trying make custom simple form wrapper avoid hassle of adding tons of code simple input. second occurrence input 1 can't quite right. here html form shown:

<div class="form-group radio_buttons required work_order_end_task">   <label class="radio_buttons required col-sm-2 control-label"><i class="fa fa-check-circle text-danger"></i> end date</label>   <div class="col-sm-2">     <div class="input-group">       <span class="input-group-addon border-none">         <input class="radio_buttons required" type="radio" value="date" name="work_order[end_task]" id="work_order_end_task_date">       </span>       <input disabled="" type="text" value="" name="work_order[end_date]" id="work_order_end_date" data-provide="datepicker" data-date-format="yyyy-mm-dd" data-date-clear-btn="true" data-date-today-btn="linked" data-date-orientation="auto right" data-date-today-highlight="true" class="date required form-control left-border-rounded">       <span class="input-group-addon">         <i class="fa fa-calendar"></i>       </span>     </div>     <br>     <div class="input-group">       <span class="input-group-addon border-none">         <input class="radio_buttons required" type="radio" value="number" name="work_order[end_task]" id="work_order_end_task_number">       </span>       <input class="numeric integer form-control" type="string" value="" name="work_order[count]" id="work_order_count">       <span class="input-group-addon">         occurrence(s)       </span>     </div>     <br>     <div class="input-group integer optional work_order_count">       <span class="input-group-addon border-none radio_buttons optional work_order_end_task">         <span class="radio">           <label for="work_order_end_task_none">             <input class="radio_buttons optional radio_buttons" type="radio" value="none" checked="checked" name="work_order[end_task]" id="work_order_end_task_none">           </label>         </span>       </span>       <input class="string optional form-control" type="text" value="" name="work_order[count]" id="work_order_count">       <span class="input-group-addon">occurrence(s)</span>     </div>             <br>     <div class="form-group radio_buttons optional work_order_end_task"><div class="col-sm-10"><span class="radio"><label class="static-radio" for="work_order_end_task_none"><input class="radio_buttons optional" type="radio" value="none" checked="checked" name="work_order[end_task]" id="work_order_end_task_none">indefinite</label></span></div></div>   </div> </div> 

the issue spans , labels being added. here code:

<%= f.input :count, wrapper: :input_group %>   <%= f.input :end_task, as: :radio_buttons, wrapper: :radio_addon, collection: [['','none']], label: false %>   <%= f.input_field :count, as: :string, class: "form-control" %>   <span class="input-group-addon">occurrence(s)</span> <% end %> 

and wrappers:

  config.wrappers :input_group, tag: 'div', class: 'input-group', error_class: 'has-error' |b|     b.use :html5     b.use :input, class: 'form-control'   end    config.wrappers :radio_addon, tag: 'span', class: 'input-group-addon border-none' |b|     b.use :html5     b.optional :readonly     b.use :input, class: 'radio_buttons'   end 

so how rid of <span class="radio"> , <label for="work_order_end_task_none"> on radio buttons , classes ( integer optional work_order_count example) being inserted wrappers , inputs?

i think figured out (sort of):

  <span class="input-group-addon border-none">     <%= f.radio_button :end_task, 'number', label: false %>   </span> 

works charm. still add custom wrapper avoid having manually add wrapper span not seem work.
