Customizer Control: Arbitrary HTML

Sometimes it’s really useful to be able to output HTML in the Customizer that’s not a label or description for a specific control. You may want to output a line break, an image, a button, or simply some additional text.

There isn’t a native Customizer control in WordPress to do this, but you can add your own custom control to output arbitrary HTML. This was a request for the Customizer Library, and the GitHub issue explains the thought process behind the code.

Custom Control

Creating a custom control to output arbitrary HTML is just a few lines of code (label and description could even be removed if you don’t need them):

if ( class_exists( 'WP_Customize_Control' ) && ! class_exists( 'Prefix_Custom_Content' ) ) :
class Prefix_Custom_Content extends WP_Customize_Control {
// Whitelist content parameter
public $content = '';
* Render the control's content.
* Allows the content to be overriden without having to rewrite the wrapper.
* @since 1.0.0
* @return void
public function render_content() {
if ( isset( $this->label ) ) {
echo '<span class="customize-control-title">' . $this->label . '</span>';
if ( isset( $this->content ) ) {
echo $this->content;
if ( isset( $this->description ) ) {
echo '<span class="description customize-control-description">' . $this->description . '</span>';

It’s kind of odd to register the setting since it isn’t actually needed, but WordPress requires a setting in order to output the control.

Output in the Customizer

Once your custom control is loaded, you can output HTML via the Customizer like this:

$wp_customize->add_setting( 'example-control', array() );
$wp_customize->add_control( new Prefix_Custom_Content( $wp_customize, 'example-control', array(
'section' => 'title_tagline',
'priority' => 20,
'label' => __( 'Example Control', 'govpress' ),
'content' => __( 'Content to output. Use <a href="#">HTML</a> if you like.', 'textdomain' ) . '</p>',
'description' => __( 'Optional: Example Description.', 'textdomain' ),
) ) );
