Hello Karl-Heinz Garber,
To add the box beside the logo, you would need update hook ‘business_point_header’ and add the new section.
To do this, first create a child theme.
In the functions.php file of the child theme, add the code to remove the business_point_header and then to add your custom header you would need to add the new action.
add_action('init','business_point_header_action_cust');
function business_point_header_action_cust(){
remove_action('business_point_header','business_point_header_action');
add_action('business_point_header','business_point_header_action_new_design');
}
function business_point_header_action_new_fun(){
//-- Copy the content of 'business_point_header' from YOUR_SITE_ROOT/wp-content/themes/business-point/includes/hooks.php and paste it here
//-- Make edits as per your need
}`
This will override the hook using the child theme.
Thank you
