So I am trying to achieve it with php. But I can only seem to add classes to the input container. Which is not helping my bootstrap integration. I am using less for all the style adjustments that work beautifully with gravity forms. It's just that I would like to customise the input size across different forms, and add classes to the inputs. I know I could use this code below and add another style to the bootstrap. <pre><code>// ADD CLASS TO SIDEBAR INPUTS add_action("gform_field_css_class", "sidebar_custom_class", 10, 3); function sidebar_custom_class($classes, $field, $form){ if($form["id"] == 2 && $field["type"] == "text"){ $classes .= " input-block-level"; } return $classes; }</code></pre> I'm curious if I can add classes to inputs directly to save the hassle of adding more styles. Thanks
