Reducing list

Dear All,

Hopefully this is an easy question.

Imagine I have an structure like this


Element X Which has 0...n children Elements Y each of which in turn has
0...n children Elements Z each of which has content I am after.


What I need in a form is:

1) To have a drop down list box showing all Y elements sorted
alphabetically. 
2) Typing into this drop down list box should give a reducing list i.e.
typing the letter r would give me all the Y elements starting with the
letter r, then typing a would give me the all Y elements starting with
the letter ra etc.
3) Finally selecting the Y element name I want should then populate the
second dropdown with the Z elements which are children of that Y
element.
4) Same as 2 but for the Z elements.
5) Selecting the right Z element should then give me the content of that
Z element.


Any ideas?


TIA

Adam
