Multiple select for multiple groups
We have a set of devices that belong to different groups. Each device generates multiple time-series data streams that can be visualised. All devices in the same group have same data streams.
For example:
Group 1:
Devices:
Device 1
Device 2
Device 3
Streams
Stream 1
Stream 2
Stream 3
Group 2:
Devices:
Device 1
Device 2
Streams
Stream 1
Stream 2
A user can select devices from each group with their streams. What would be the best way to let a user navigate through such selection?
Presently, we're thinking for two dropdowns for each category, one for devices and the other for streams.
