Acrobat Pro DC Dependent Dropdowns

Question

I have 2 dropdown lists on my pdf form named, "Category" and "Items". I need to make the "Items" List dependent on the "Category" List. The "Category" List items are "Fruits", "Veggies", "Other". If you select "Fruits", then the "Items" list would contain a list of fruits. If you select "Veggies", then the "Items" list would contain a list of vegetables, etc.

I understand that I need a Javascript to make this happen, but alas, I do not know how.

Your help is appreciated.

In "Category" field->properties->options tab tick 'Commit selected value immediately', use script in "Category" field as validation:

var f = this.getField("Items");
switch(event.value){
case "Fruits":
f.setItems(["Banana","Apple","Lemon","Orange"]);
break;
case "Veggies":
f.setItems(["Tomato","Cabbage"]);
break;
case "Other":
f.clearItems();}

"Other" choice will clear items from "Items" field, if you want something else under "Other" choice let me know.

In this link PDF Form JavaScripts Dependent Dropdown Menus the video shows how to create dependent dropdown menus using vegetables and fruits as an example.

There are different ways you can achieve the same results with JavaScript scripting, and I've seen this answeered before many times in these support forums and outside these forums.

See another useful way published by ACP Joel Geraci in this other link: Acrobat Javascript&colon; Change list values based on another list
