Right, that works for LI and sub-lists. But how do you
query from JS the state of such a list item, expanded or
collapsed ? Checking the computed value of the display
property on all children of that LI is not a workable
solution.

We need to be able to query 'something' directly from the LI.
That means a solution based uniquely on the display property
of the children is not enough. We need an attribute on the LI
or a unique CSS property setting the expanded/folded status
of the item.
