I want to place a form inside a tooltip, but CSS-only tooltips are something like this:

<a>Anchor<span>Tooltip content here</span></a>

...which of course would be this:

<a>Anchor<span><form>form content</form></span></a>

...which works, but apparently isn't good standard.

What do I do?

I want to put any HTML, including <div>'s in the tooltip.
