We discussed this last week
and HTML5 is certainly a step forward in this respect.
Still, HTML5 doesn't allow <input> everywhere in the document.
For visible input fields this is of course a good thing, but
for hidden input it would be good to have more flexibility.
My use-case is a server-side solution that is to automatically
add hidden postable state to just about any HTML fragment (the
<form> is taken care of on an outer level). To make this in a
valid way today presents quite a few challenges like
traversing table models or adding extra <td>:s just for state.
I don't have any universal solution, but possibilities include:
- allowing hidden <input>:s to actually live anywhere (this is
probably hard to do dtd/validation-wise)
- inventing some hidden postable state that is orthogonal to the
element structure and thus can be added to any element (maybe
an extended version of the data attributes?)
- keeping the whole thing invalid but still define in HTML5 how
the migration of ill-placed <input>:s should work
(I did a little research on the last point here:
Do you have comments or any other ideas?
