I have a page where I am displaying past projects at the bottom.
I want the page to allow selection of the past projects.
I added 3 x Page Link Objects to the page so that the client can select the page from the list of pages.
I need the page IDs to pass to WP Query.
What is the best way to
a) Allow the client to select Projects from an easy dropdown (Like the current Page Link interface)
b) retrieve the page ID for me to use in a WP Query?
