I have created a Field Group which I wan't only to show up on two Pages. But when I try to create a rule in Edit Field Group > Settings > Advanced location rules I can't select "Post ID" (there is no such option). If I select "Post", then I can only select a page among 10 pages in the drop down, and I can't find the page I am looking for (and the page I am looking for has the title "Försök", which is the same title as another page with a different slug).
Thanks! Yes, I can see now that searching works. The reason I missed it was because the Page title I was searching for didn't look as expected. Instead of the title "Försök", your select box showed the title as "<mark class='searchwp-highlight'>Försök</mark>". Yes I use the plugin SearchWP. But if I go to Pages, the title shows up as "Försök" and in DB the field "post_title" in table "wp_posts" is also "Försök".
So, why is the <mark>-code showing up in your Select box?
