Can different pages show different SW Popup Panel content?

Yes. You can match each popup item to a page body class:

1. In SW Popup Panel, open Content Items → Label & Body Class and enter a short label that can also work as a body-class token.
2. On the page, open Page contents → Hidden modules → Body Class.
3. Enter the same token, then preview the page to confirm that the intended popup appears.

Use a simple lowercase token with hyphens instead of spaces or punctuation so the two values match cleanly.
