I’ve got a special project for form-based data entry that I’d like to

in one drop-down list affect the options available in a second,
otherwise unrelated, drop-down list?
Nice puzzle to solve.
I would say yes, but not using a normal combo-box, using a "hand-made
combobox" (= text-field + command-menu + custom macro-command).
Simply send me a sample first list (XML + CSS) because I need to understand:
1) From which source (CSS generated content? the XML document itself?
external file?) you get the items of the master list and slave list?
2) When the user picks an item from either master list and slave list,
where does this item go (in the XML document)?
If you answer these questions, I'll try to create a demo, just for the
fun, next week after we release XMLmind XML Editor v7.2.

Alternatively, the selection made in one drop-down could affect the
visibility of another; e.g. if I have 9 options in my first drop-down,
and I have 9 lists in another part of the form relating back to the
selection made in the first list, can I hide all but the relevant list?
This is probably possible too, but much less elegant.
Once again not using a normal combo-box but using a "hand-made combobox"
(= text-field + command-menu + custom macro-command).
Depending on the item selected in the master list, the custom
macro-command would unset a custom property (e.g. "foo") in the
currently displayed slave list and would set it on another slave list.
The CSS would contain rules vaguely resembling:
slave_list {
display: none;
}
slave_list:property(|foo) {
display: block;
}

Got any recommendations for how to address this?
