Handling Dropdown conditional Dropdowns
I'm working on a material design web-app designed for a mobile/touch environment.
Naturally I'm very pushed for space and would like to know what the best-practice is for conditionally providing a sub-set of options.
I don't really like the idea of showing two selects only when the appropriate option is selected
Example:
- Option 01
- Option 02
- Option 03
- Option 04
- Option 05 (only this has the "sub-options" i.e. [sub1, sub2, sub3, sub4, sub5]).
more info about the context: these are a sort of preferences ...options in this case are different kinds of visualizations but the option number five has a more detailed visualization divided by areas
