No way would I want an expandable checkbox. It should fail a validator. Browsers let things like this pass because it is too expensive to correct every possible poorly coded web page. They need to try to be performant. This is a validator issue. Rich Sent from my iPad > On Feb 3, 2016, at 1:42 AM, Schnabel, Stefan <stefan.schnabel@sap.com> wrote: > > To be used in which pattern?
