Hello everyone
How can I show, for example, all the brazilian cities in one list?
There are more than 5000
I tried group by state, but it doesn't work because it is too big
I want something like this
If o choose RJ (state)-> there will be List with all cities in Rio de Janeiro (500 itens +-)
If o choose SP (state) -> there will be List with all cities in Sao Paulo (600 itens +-)
...

Like this image (It is wrong because it haven't all cities)
Can someone help me?
Thank you in advance
