Is there anyway to generate a list during the configuration based on what is put in the first grouping? I know for example the Google Analytics connector has Account-> Property -> View which you have to select before you are setup.
I'd like to create a connector where if you put in a web address it pulls in a list of the end points for that specific site which are listed in a json file.
Update (2020/05/05): This can now be achieved through Stepped configuration in Community Connectors.
Original: Right now, the configuration is not dynamic.
That means you cannot pull in data from external sources during the configuration or update configuration values based on something already selected in the configuration.
The alternative now is to have flat lists of selections.
This might get updated in future.
