The shell expands *html to a list of html files in the current
directory. IOW, you explicitly gave grep a list of html files
to search. The -r flag does nothing in that case.
You appear to want to search all files underneath the current
directory who's name matches the shell glob pattern "*html".
If that's the case, then what you meant to say was:
find . -name '*html' | xargs grep hmenu

Again, you gave grep an explicit list of files to search, so
the -r option doesn't do anything. In this case, it's not
obvious what you intend, so I'll refrain from guessing.
