content show after the faq instead before

hi, to fix this issue you need to return the output instead echoing it directly.

you can fix it by this:

// start output buffering
ob_start();

// shortcode output here!!!

// save output buffering
$output = ob_get_contents();
// delete output buffering
ob_end_clean();

wp_reset_postdata();
return $output;
