<div class="form-group"> <label class="control-label col-sm-4">Description<span class="required"> * </span></label> <div class="col-sm-8"> <input type="text" name="name" data-required="1" class="form-control" aria-required="true" aria-invalid="true" aria-describedby="name-error"> <span id="name-error" class="help-block help-block-error">This field is required.</span> </div> </div>
