I came here to post about this very subject today!
It does seem a little, how can I say, half-baked that the
snippets only work outside of the drop downs...
I have a page with about 20 snippets on, each in its own drop
down. I achieved this by putting the snippet on the base layer of
the page then cut and pasting it into the drop down...
But now when I close this page, and then re-open it in RH, I
don't see my snippets any more... then I did a build and found that
they are actually still there in the output! (at this point I can
go to the properties of the snippet, click Used In and see that it
is still used in the page)
Then I went back and edited something on this page, and did
another build, all the snippets had snipped off into thin air!
Snippet properties now show that it is not used in the page any
more...
Very fustrating!
So now it seems if I want to edit something on a page which
has a snippet inside a drop down, I have to re-add the snippets to
the page each time!!!
Has anyone else seen this "feature"??!
