In some cases, themes must display parts on a page that do not use the Bootstrap container or CSS. For example, see the following homepage:

Custom Row on the Front-End
Custom Row on the Front-End

The “birds” slider extends across the entire width of the browser, whereas the Bootstrap grid is contained inside a frame.

Layouts allows the implementation of such structures using Custom Rows. They appear in the Layouts editor as an entire row. They can be moved up and down; however, not left or right.

When a Custom Row is displayed on the front-end, the following occurs:

  1. The Bootstrap container DIV is closed (after the preceding Bootstrap rows).
  2. The Custom Row is displayed.
  3. The Bootstrap container DIV is re-opened (for the following Bootstrap rows).

Creating a custom Custom Row

To create a Custom Row, first create a dd-layouts-cells folder inside the theme’s main folder. Inside the dd-layouts-cells folder, create a PHP file for the Custom Row and any other files and folders necessary for the custom functionality (e.g., stylesheets, scripts).



Call register_dd_layout_custom_row() to register the Custom Row:

register_dd_layout_custom_row( $custom_row_type, $args )


  • $custom_row_type – String identifier. This is used to identify the new Custom Row.
  • $args – Array of arguments:
    • name – Name of the Custom Row;
    • description – Description of the Custom Row (optional);
    • custom-row-content-callback – Function name of a callback function that returns the HTML to be rendered in the front end.


  • true – on successful registration;
  • false – when a problem is encountered. Typically, the Custom Row has been registered previously.

An example of this process follows:

Register Custom Row
function register_custom_row_carousel() {
	if ( function_exists('register_dd_layout_cell_type') ) {
		register_dd_layout_custom_row ( 'register_custom_row_carousel',
			array (
				'name' => __('Owl Carousel', 'wpbootstrap'),
				'description' => __('BootStrap Theme Owl Carousel.', 'wpbootstrap'),
				'custom-row-content-callback' => 'custom_row_carousel_content_callback'
add_action( 'init', 'register_custom_row_carousel' );

Now, we must design the output of the Custom Row. We accomplish this using the callback function:

Custom Row Output
function custom_row_carousel_content_callback($custom_row_settings) {
	wp_enqueue_style ( 'owl_carousel_main_css', get_template_directory_uri() . '/dd-layouts-cells/css/owl.carousel.css', false, NULL);
	wp_enqueue_script ('owl_carousel_row_js', get_template_directory_uri() . '/dd-layouts-cells/js/owl.carousel.row.js', array('jquery'), WPDDL_VERSION, true);
       $content = '<div id="owl-demo" class="owl-carousel">';
	for($x = 0; $x <= 8; $x++) {
		$content .= '<div class="item"><img src="' . $x . '.jpg"></div>';
        $content .= '</div>';

return $content;

Adding a custom Custom Row to your layouts

Once created, a Custom Row can be added to a layout.


Insert Custom Row Step 1 1. In the location where you wish to place the Custom Row, click on the “down arrow” next to the “+” icon for adding rows.
Insert Custom Row Step 2  2. In the drop-down menu of row options, click on the Add custom row.
Insert Custom Row Step 3  3. In the creation dialog that opens, choose your Custom Row in the drop-down menu and then click on the Create and close button.

Because a Custom Row is a row, it can be dragged up and down. To demonstrate this on the example, move the newly created Custom Row to the top of the page, before the header.

Differences Between Custom Rows and Cells

Both Custom Rows and Custom Cells allow the addition of custom functionality and markup to themes. There are, however, important differences:

  1. Custom Rows display outside the Bootstrap grid. As rows, they can only be moved up and down inside the layout.
  2. Currently, Custom Rows do not offer a GUI allowing users to set their properties.
  3. Custom Rows cannot be resized or displayed next to other cells.
