Hi!

The data I have can be categorized for example in two categories;
category X and Y (+ time)
The problem however is that I would like to have some kind of dynamic
drop-down menu for my second option (category Y) which changes based
on the choice of X.

The problem is that right now, I have 20 X items, but let's say 1000 Y
items, so to go through the whole list of 1000 is a bit tedious when
making selections. So I was thinking, that a much more elegant
solution would be to have the content of the Y menu change based on my
choice of X, thus narrowing the list to about 50 (if the Y's are
evenly distributed/connected to the different X's)

To me it sounds like a simple piece of code, but can it be done?
Examples?

BR,
Josip
