Hi there. Welcome to Bubble.

The Group element is the concept you are looking for here.

A Group is … a Group of other elements (including other Groups) or related information.

The Group, in your case, would be driven by the Current User’s data.

So you could create a Group for “Back pain in the over 50s” and set it to be hidden. A condition on the group would then only show this group when the User had “Back Pain” as something they suffer with and their age > 50.

If you lay these groups out in a big long list on the page, and set them to “collapse when hidden” you could even show multiple groups on the page at once.
