By default there is no option to select a page and duplicate it in WordPress. This is because pages are unique entities with their own metadata and URL. But you can create a new page, copy text from the former page, and paste it into the new page. That's the only way to copy content directly.

Adding JavaScript directly to a WordPress page or post is forbidden, even in text mode. So this would happen in any site, not just in BoldGrid. I'd advise checking to see if Facebook has a plugin to support the addition of this script on pages you select. Or, using a plugin like Advanced Custom Fields, you can add advanced metadata to posts and pages.

Yes, you can use plugins. But note, some plugins may conflict with other plugins, which is true for any WordPress site.

Does this code need to be individual pages or on each page? If the latter, it would be best to add it to a template file using either a plugin or in a child theme.

It's up to you as far how you want to organize the various sites. It's outside of the scope of the BoldGrid plugin itself. This is more of a general WordPress issue.

It's possible there's a conflict between the two. I'd advise submitting this query as a bug report.

If I understand you correctly it sounds like you want hyperlink the images in a gallery to a custom gallery for each image. The easiest way to do that may be to create the unique galleries first and then link to those pages individually from the images on the landing page.

You can change the link for individual images using the "Gallery Settings" in the Media Library. 

Unfortunately, BoldGrid does not have phone support. However, if your host supports BoldGrid, you may be able to contact their support team. If not, you can also submit a support request via BoldGrid Central > Manage My Account > Support Request.

There is a button to add or delete columns on the drag handles. Scroll down to the "Columns" section of our full guide on editing pages in BoldGrid and you'll see detailed instructions.
