Select multiple in cascading

Greetings Kobo toolbox Team
I am creating with “select multiple” cascade to come the next category automatic until I will finish filling the data to collect. However, when I select all the first categories, the next category couldn’t give an option.
Example; The first category is 4 years (2020,2021,2022,2023) and the next category is 12 months. I want to come the month option, automatic after all years selected once.

Welcome to the community, @hadish! Could you show how the process and choice should flow? Could you show/write how the choices should display once you select anything? The community should be able to help you more precisely based on the details you share.
