Description
You can use or placeholders to let the renderer know where where the element label or the element html are positionned according to the required tag. They will be replaced accordingly with the right value. You can use the full smarty syntax here, especially a custom modifier for I18N. For example: {if $required}<span style="color: red;">*</span> will put a red star in front of the label if the element is required and translate the label.
