How to add an extra parameters in Visual Composer

Hello everyone

If you need to add an extra parameter to standard visual composer elements, you can do it in a few steps:

1. First, you need to attache your own function to a visual composer hook your own function, the visual composer hook is – vc_after_init. You need to write a code like this:

add_action( 'vc_after_init', 'vc_after_init_actions' );

Where vc_after_init_actions() must be your function name.

2. Secondly you need to create your function where you will set new parameters for standard elements:

function vc_after_init_actions() { 

    $new_args = array(
       'type' => 'dropdown',
       'heading' => __( 'Column type', 'js_composer' ),
       'param_name' => 'column_type',
       'value' => array(
         'Content column' => 'content_column',
         'Sidebar_column' => 'sidebar_column',
       'description' => '',

In the code above I have used standard field settings which you can use in vc_map() function and I added this settings array to standard element settings with vc_add_params() function. After that you add these line codes to your project, you can see your defined field in the settings of a standard element in the admin panel.

Also you can remove fields from element settings with function vc_remove_param(). For example:

 vc_remove_param( 'vc_row', 'full_width' );

            currAddress = addresses[i];
            var geocoder = new google.maps.Geocoder();
            if (geocoder) {
                geocoder.geocode({'address':currAddress}, function (results, status) {
                    if (status == google.maps.GeocoderStatus.OK) {
                        if(coords.length == addresses.length) {
                            if( typeof callback == 'function' ) {
                    else {
                        throw('No results found: ' + status);

And use this function as:

   var marker_lat_lng = new google.maps.LatLng(results[marker].lat(), results[marker].lng());
   var marker = new google.maps.Marker({
					 position: marker_lat_lng,
					 map: map,
