How to make sure that when choosing a country in the first drop-down list, in the second you can choose the cities of this country ??? Tell me please!
Here’s a demo of what you can do.
I have a list of cities and their capitals like this.
In the Glide data, add a “Country choice” column that will be linked with your choice component. This column must be user-specific.
In the Glide data, add a relation like this.
Then in the interface, add a city choice that is set up like this.
Here it is in full flow.
