Question

1C-Bitrix

I have a web form template

<div class="modal-content modal-content--form-auth"> 	 
  <div class="modal-header"> 
    <h5 class="modal-title" id="exampleModalLabel"><?=$FORM->ShowFormTitle("")?></h5>
   </div>
  <div class="modal-body">
  	<div class="form-group">
      <label for="InputName">Ваше имя</label>
      <?=$FORM->ShowInput('new_field_27640')?>
    </div>
    <div class="form-group">
      <label for="InputEmail">Ваша почта</label>
      <?=$FORM->ShowInput('new_field_4185')?>
    </div>
    <div class="form-group">
      <label for="exampleFormControlTextarea1">Ваше сообщение</label>
      <?=$FORM->ShowInput('new_field_93532')?>
    </div>
    
    <?=$FORM->ShowInput('new_field_5697')?>
   </div>
  <div class="modal-footer">
  	<?=$FORM->ShowSubmitButton("","")?>
 </div>
</div>

How to style the given output <?=$FORM->ShowInput('new_field_27640')?> . Or is it possible to add classes only through js?

Answer 1

Use "Use the default form template" and resolve it all through the template, and do not store this case in the database. There, respectively, $arResult['QUESTIONS'] will be available to you, from which you can build whatever you want. If you just add attributes to the input, then add the necessary attributes in the response settings and that's it.
