Hello,
I am trying to create a menu-like window which pops up when the user
interacts with a search field in a modal window. I have created an
example which you should be able to compile after copy & paste (if the
mail client doesn't break the lines). What I need help with is how to
get the green window behave like a modal one (as far as not letting the
main window with the "Click me" button work), but let the button in the
search popup work.
Thank you in advance,
/Daniel
