There is a thing, I'm missing in HTML for a very long time. I think I've read this somewhere here, but I don't find it.
What I would like very much is the possibility to have checkboxes / radiobuttons that control other checkboxes / radiobuttons.
For example I activate (deactivate) one checkbox and this activates (deactivates) other checkboxes too.
I know that such hierarchical / interdependent checkboxes are possible with Scripting. But for those who have Scripting deactivated (and maybe even cannot change this, e.g. at work or school) that isn't an option.
This feature should be possible only with HTML and CSS!
