Hey Plamen,
No need for a widget here. You should be able to display a list view of the resulting countries for the user to select from in step 2.
If you did want to use a widget I'd recommend checking out this one:
Best of luck,

Reference selector → default from mendix
- Organize your domain model with continents and countries. They should be dependent already. Lets call it master data
- From the page, you need to have an entity that is linked to continents and countries
- When continents are selected, you could use constrained by on the country selector and use continent, to show the countries of only selected continents
- After choosing country, you could create a new entity and associate it with selected countries to capture the rating per user on that country level
Could you recommend me a widget to achieve such a functionality?
