Looking at the documentation expalining the use of client side menus, including the drop down menu.
I was messing around trying to get the "Open", once clicked, to use javascript to open windows file explorer to open/pick a file.
I've got it to partially work... Using keystrokes Ctrl-O will open the file explorer yet clicking on the drop down's File/Open does nothing.
Not sure what I'm doing wrong here.
NOTE: I had commented out the two &html lines in the Testing Method... and doing a Ctrl-O still work.
Why?
