Unfortunately, Travelo theme has not such feature.

Please edit /wp-content/Travelo/templates/modern/footer.php file.

You can find following code in the file.

<div class="row">

    <div class="footer-widget-1 col-lg-4 col-md-6">

     <?php dynamic_sidebar( 'sidebar-footer-1' );?>

    </div>


    <div class="footer-widget-2 col-lg-2 col-md-3">

     <?php dynamic_sidebar( 'sidebar-footer-2' );?>

    </div>


    <div class="footer-widget-3 col-lg-2 col-md-3">

     <?php dynamic_sidebar( 'sidebar-footer-3' );?>

    </div>


    <div class="footer-widget-4 col-lg-2 col-md-3">

     <?php dynamic_sidebar( 'sidebar-footer-4' );?>

    </div>


    <div class="footer-widget-5 col-lg-2 col-md-3">

     <?php dynamic_sidebar( 'sidebar-footer-5' );?>

    </div>

   </div>

And replace with following code.

<div class="row">

    <div class="footer-widget-1 col-md-4">

     <?php dynamic_sidebar( 'sidebar-footer-1' );?>

    </div>


    <div class="footer-widget-2 col-md-4">

     <?php dynamic_sidebar( 'sidebar-footer-2' );?>

    </div>


    <div class="footer-widget-3 col-md-4">

     <?php dynamic_sidebar( 'sidebar-footer-3' );?>

    </div>

   </div>

And you can add widgets to sidebar footer 1, 2, 3 in Appearnce -> Widgets menu.

And please add copyright information to the file.

Best regards,

1. I want to change the default footer column to 3 columns
2. How to add copyright information to bottom of footer.

Thanks.
