The text that starts:

Architecten, interieurdesigners, vormgevers …

What about the title? and the breadcrumbs?

And you want to stay on that page? This means the display of the text needs to be conditional, and that means that you would need to output the text conditionally using PHP (the PHP needs to detect if a search has been made). The safest way to do this is to create the PHP as a shortcode and place the shortcode in to a Visual Composer (Page Builder) Text element.

This plugin allows you to create a shortcode with PHP in it:

The PHP would look something like:

global $searchandfilter;
$sf_current_query = $searchandfilter->get(187)->current_query();
if ((!$sf_current_query->is_filtered())&&($sf_current_query->get_search_term()=="")) {
  echo '<div>Nothing to see here folks!</div>'; 
} else {
  // your page title, breadcrumbs, text here
}

That is the theory of it.

Ah. I understand. What do you have the Scroll Window to setting set to? See here:

I think it might need setting to Custom with the selector being .vc_grid-container-wrapper

Can you make a screenshot of the settings on that section and post me a link to the image?

Where you have #s maybe try as I suggested, .vc_grid-container-wrapper

Sadly not, as the control of the page is handled by WPBakery’s plugin.
