I'm kind of new to WP but I've been developing for many years. The way WP segregates pages and posts is driving me crazy. I'm trying to get a main story on the HP with a 3-column grid beneath that that displays an excerpt (title, thumbnail, excerpt, button) of three other pages I select and in a particular order. Not post excerpts; page excerpts. I could statically build this into the main article but this would only confuse the client. Can I use PixGridder to add 3 columns beneath the main HP article and use a short code or some other method to get an ordered series of page excerpts to appear there? If it helps to know, I'm using a solostream theme called Prosper. Thank you.
