Nested HTML FORMs

It is possible to have multiple forms within the same Html document but it is NOT possible to have a Html Form nested within another Form. See the W3C Html Form for reference. This is a fact that has escaped my memory once or twice throughout my time been a web developer so to avoid wasting time it's important to remember this basic rule.

Is there a way around this? The short answer is yes using javascript and html which isn't really a nested form but behaves like one. This jQuery nested form solution is a pretty neat way of doing it.
