A generic range with value control you can use to replace the range control.
I've added this control to my customizer demo theme.
Clone this repository and include the class:
/**
* Check for WP_Customizer_Control existence before adding custom control because WP_Customize_Control
* is loaded on customizer page only
*
* @see _wp_customize_include()
*/
if ( class_exists( 'WP_Customize_Control' ) ) {
require_once( dirname(__FILE) . '/class-customizer-range-value-control.php' );
}
$wp_customize->add_control( new Customizer_Range_Value_Control( $wp_customize, 'my_control', array(
'type' => 'range-value',
'section' => 'my_section',
'settings' => 'my_settings',
'label' => __( 'Width' ),
'input_attrs' => array(
'min' => 1,
'max' => 240,
'step' => 1,
),
) ) );
