Cascading List box (Not Drop down list box) issue

I am new to PDF forms.


I created three list boxes. Master List box, Frist Dependent List box, Second Dep List box.

Master List box  >> First Dependent List box  >>  Second Dep List box.


I am trying to populate First Dependent List box based on selected item in Master List box. And trying to populate Second Dep List box based on item selected in First Dependent List box.

When I select Master List box item, the First Dependent List box items changes accordingly.
However I am unable to list any items in Second Dep List box and also unable to view any items in Second Dep List box when I select any item in First Dependent List box.

 

I want :
When Master List box item is selects, the First Dependent List box item should change. And when I select First Dependent List box item, the Second Dep List box item should appear/change.

 

Master List Box >> First Dependent List Box >> Second Dep List Box
Example: Europe >> France >> Paris

 

Can anybody please help me with the code for three or more List boxes code.

I found multiple examples of Cascading drop down list box and I tried to modify them for Cascaded List box however Drop down List box code does not work for Regular List box.

Correct answer Nesa Nurani

I writed in my post to put code in list box, code is for "selection change". 

I think OP wants a list box and not a dropdown to act as cascade (select item in master list-then select in first dependent list and then in second dependent list)

See if something like this works for you:
Put code in Master List Box:
var list1 = this.getField("First Dependent List Box");

if (event.value == "Europe") {
list1.clearItems();
list1.insertItemAt("France");
list1.insertItemAt("England");
} else if ( event.value == "USA"){
list1.clearItems();
list1.insertItemAt("Texas");
list1.insertItemAt("Utah");
}else list1.clearItems();

 

Put code in First Dependent List Box:
var list2 = this.getField("Second Dep List Box");

if (event.value == "France") {
list2.clearItems();
list2.insertItemAt("Paris");
list2.insertItemAt("Lyon");
} else if (event.value == "England"){
list2.clearItems();
list2.insertItemAt("London");
list2.insertItemAt("Liverpool");
} else if (event.value == "Utah"){
list2.clearItems();
list2.insertItemAt("Salt Lake City");
list2.insertItemAt("San Juan");
} else if (event.value == "Texas"){
list2.clearItems();
list2.insertItemAt("Dallas");
list2.insertItemAt("Houston");
}else list2.clearItems();

    Nesa can yuo explain where to run this code? 

     

    The OP has repeatedly referred to Cascading Dropdown Listbox and Regular Listbox creating confusion with these terms.

     

    Listbox and combobox (or dropdown menu) are two different things. And yes the OP is right when observing that the code varies slightly if it will be  run from a Listbox not a combobox.

     

    If it is a listbox, is that script used as a Mouse-up event or is it used as "Selection Change" script?

     

    If it is a dropdown menu is it a custom format script  or a custom keystroke? Or is it a combination of both format and keystroke scripts?

    You need to share your code.

     

    Is hard to tell what is wrong without taking a look at it.

     

    Also, you keep referring to cascading dropdown lists.
