how to get the data from a lsit to another drop list

Question

I am building a form.

Like Category form fields/drop list where contains around 10-12 categories. Each category has around 15-20 products.

My aim is to get the drop list when a category. i.e "Jersy" is selected in dropdown 1, and then get the 10 jersey model in dropdown 2.

Mine is Acrobat pro-DC 2020.

Any help would be appreciable.

The basic code to do it is something like this (as the custom validation script of the first field):

if (event.value=="Jersey") this.getField("dropdown 2").setItems(["Jersey model 1", "Jersey model 2", "Jersey model 3"]);
