drowdown lists

Good day,

I'm new to this forum, and really hope somebody could help me, as I've been searching Google endlessly the last few days.

I'm writing an app where you can choose a location, ex. grocery store, petrol station, and also a scenario like asking if you can pay by card. The scenario then gets translated to another language. What I'm trying to accomplish is the following:

I would like to select a location from a drop down list, which in turn would give me options for that selection in a second drop down list. example:

1. select grocery store from first drop down

2. second drop down must populate with scenarios that you would use in a grocery store

3. Select petrol station from first drop down

4. second drop down must populate with scenarios that you would use at petrol station.

Hope that's plenty of info to support my request...!

Kind Regards,
