Menu link to “Page in Page” Content

[ Moderator note: moved to Fixing WordPress. ]

Hello Everyone,

I am hoping to get some help with this issue:

I am building a page that will have a menu in one Section and content in the other. I want to have the menu be static and the page be static – i.e., they will not redraw when you click a menu item…rather, the content will simply display in the second Section based on what is selected.

I can obviously do this by creating pages for the content and duplicating the menu in each page, but I would like to not have each page redraw the menu and instead have only the content in the other section change.

I do need to create the content into pages as there will be close to 100. Tried looking into a page-in-page idea…but still doesn’t help with what to put into the URL to make the page display the content page in the Section without redrawing everything.

I used to do this eons ago by targeting frames in HTML, but have no clue where to begin with accomplishing this in WP today.

Thanks in advance for your advice. ??
