Mount local folder, over already mounted remote folder (best approach)

Please tell me if it's possible to mount LOCAL folder, over already mounted REMOTE folder?

I would like to achieve something like below folder structure:

-remote: /mnt/dropbox/
-remote: /mnt/dropbox/program/
-local: /mnt/dropbox/program/temp/

Thank you!

You can use a bind mount to mount local folders - I think (but not 100% sure) that this will work when mounting over a FUSE mount.

Mount over top of of another mount is generally a very bad idea as you are hiding things.

Depending on your order of operations, if something writes to /

before the process happens, it gets hidden.

I'd ask a bit differently as to why / what problem you are trying to solve by doing the above.
