Drop Down Field Coding

[Guest]

I'm using Acrobat Pro and I am editing a pdf form that I have already made.  I have a drop down field with four different options (let's say 1-4). I then have a second drop down field next to it.

What I need to do is make the list of options in the second field dependent on a selection in the first drop down. (i.e. first drop down field selections are 1-4, and the Second drop down field selections are a-d, but if 3 is selected in the first drop down I want the second field options to be a-e.  Hopefully that makes sense. 

Thank you!

[I moved your question to the PDF Forms forum. The Lounge is not for technical questions.]

Yes, this can be achieved using a script. The basic format of that script would be (as the custom validation script of the first field):

if (event.value=="1") this.getField("Dropdown2").setItems(["a", "b", "c", "d"]);
else if (event.value=="2") this.getField("Dropdown2").setItems(["a", "b", "c", "d", "e"]); // etc.
else this.getField("Dropdown2").clearItems();

If you're interested in a tool that will allow you to set up such dependent drop-down fields easily, and without having to write any code, check out this one I've developed: Custom-made Adobe Scripts: Acrobat -- Create Dependent Dropdowns

Ended up using your suggestion from another thread. Ended up with this coding that seems to work fairly well.
