How change static dropdown value based on another static dropdown in orbeon forms??

[Władysław Czaja]

I mean situation like here, but values in dropdowns is not populated dynamically.

For example:

I choose P1, and in second dropdown I see only E1, E2, E3

or

I choose P2 and in second dropdown I see only E1, E2

or

I choose P3 and in second dropdown I see only  E2, E3, E4

etc.

These are just examples of how one list is filtered based on the value in the other list

Here is demo:

Hi Vlad,

Unfortunately, right now you can't do any dynamic filtering on the static values that you provide in Form Builder, but this is something we are planning to add (see RFE #4614 linked below, on which I added a +1 from you). If you need to do this right now, you'll need to either (a) use multiple dropdowns for E, in your example 3, and have only one of the 3 visible at any given point in time based on the value selected in P, or (b) for E use a Dynamic Dropdown, and delegate the generation of the list of value to a service that receives in input the value selected in P.
