Position an Ajax search shortcode below the header

Hi everyone,

I have an Ajax search plugin called AJAX Search for WooCommerce and it uses the shortcode [wcas-search-form].

I've been able to place it in the header so that it shows virtually all the time using a Hook element with position generate_inside_navigation - however this shows it above the header and I was rather hoping that it could be always displayed just below.

The priority is currently set to 50 (have tried higher) and I wonder if adjusting this is intended to reposition or if you can suggest another solution.

Any help would be appreciated.

All the best

Simon
