To show or hide Sub categories in ProductCategoryInput widget based on other drop down selection value(custom field)

Content

Hi All,

I am trying to show/hide the sub categories( Extended ProductCategoryInput widget) based on drop down value(Country custom field). I am not able to fetch the category Id from the console.

So,I am trying to fetch the Id using java script from front end side, It is working in browser console, but It is not working when I place the code in logic.js of the extended widget.

Please help me, if we can handle this issue in any other way.
