Dynamic dropdowns

[reflection95]

Hi, just wanted to confirm that for the time being there is no such functionality for a dashboard:

• 3 dropdowns for country, city, and street. user chooses the country and then in second dropdown there are only cities from selected country for choice, and so on.
  I've seen 5-10 topics already opened on that, but no solutions are working, e.g. here they suggest selecting via QRDS from a query with a parameter, which is not supported according to docs (and it doesn't work, i tried it)
