the form layout "exploded" is generated by the j-cook builder in this way:
<div class="control-group <?php echo($field->responsive)?>">
<?php echo $field->label; ?>
</div>
<div class="controls">
<?php echo $field->input ?>
</div>
this doesn't work very well, and the layout looks a bit weird.
to follow the other joomla standards on j3, it should be:
<div class="control-group" <?php echo($field->responsive)?>">
<div class="control-label">
<?php echo $field->label; ?>
</div>
<div class="controls">
<?php echo $field->input ?>
</div>
</div>
