drop down, select, scroll, select ability

[Nalini]

Please, I need detailed explanation or tutorial.

1) Do i use the drop down list component?
2) How many options should I put on the drop-down list?
3)Will my service be a list service and if so, how do convey..first look for state, then county?

If you point me to your tutorial, I'm sure I'll be able to figure this out.

We don't have such tutorial, steps are:

1. Select component http://docs.appery.io/documentation/u...
2. As your app logic requires. There should be two selects.
3. Yes.
   a) For first select on change value event invoke Service where you retrieve countries for chosen state with first select ;
   b) Result of this service should be mapped to the second select.
