Hide a field value based on condition of another field in Webform

Hi,
I want to customize a webform based on conditions.
I have services in 2 different countries. Based on the selected country I want to display different products in the same ‘product’ field. ‘product’ is a SELECT field.

So let’s say ‘product’ has predefined values:
countryA-product1
countryA-product2
countryB-product1
countryB-product2

How can I show only the products of countryA when countryA is selected in field ‘country’?

Thanks in advance!
