I'm trying to use linked filters in an R flexdashboard. I can't use RShiny due to GDPR.
I'm hoping to create the following filters:
- country
- city
- borough
- street
Where each filter will link to the next filters, meaning someone can select country as eg. "France" from a list of multiple countries and the cities would appear in the next filter as "Paris", "Bordeaux" "Marseille".. etc. Then the boroughs and streets would follow on from this, linked in too.
I have used crosstalk previously for filters (including using groups and keys) but can't find a way to link the filters together.
Does anyone know of any other methods to do this or a way within crosstalk to do this?
Any help appreciated!
