Hi,
Thank you for the details, it helps me a lot.
I think I understand what you need here, but that is not possible without using custom code, as the title is always set and the conditional fields then would not work.
Try this custom code to the functions.php in your theme/child theme directory (copy from line 3 only!). Before editing, please make sure to have a full site back-up just in case!
Scrolling fixed header question
By default, the plugin should recognize that, when initialize and should fix the results there, but in this case it fails, as the header is only fixed after initial scrolling. Using a bit of custom CSS however will help:
[php].asp_r_3 {
position: fixed !important;
}[/php]
It will still ‘jump’ once the header fixation happens during the scrolling, but it will be much smoother.
