Hi everybody,

I use ODK collect quite a while for field-data collection. Right now I'm at the point where I'd like to include a decision tree into my odk-form. I've read that this is possible with odk but not so easy.

So my question is: Does anybody has an example for me, how such a decision tree could be implemented into odk? Is it possible with odk build?

Thanks & warm greetings

Jo

Hi @jo

When you get a chance, please [introduce yourself here](https://forum.getodk.org/t/introduce-yourself-here/6671). I'd also encourage you to add a real picture as your avatar because it helps build community.

Branch/skip logic can be implemented in ODK and it's possible to code it via ODK build.
