Affects Version/s: 1.0
Fix Version/s: 1.2_09-b02
Operating System: All
The spec talks about SelectItemGroup supporting the additional property
I think that should mean properties inherited from SelectItem are supported.
In particular "escape" should be honored when rendering the label.
"disabled" should also be honored since the HTML optgroup knows a disabled
attribute and that is supported by browser just fine.
I checked with selectOneListbox and at least the html renderer for that
component just ignores these properties, see MenuRenderer.renderOptions()
