Dependent list boxes

[ppatane]

I have a list box that enters in a user's name and does specific actions based on the user chosen.  I n0w need to have a 2nd list box pop up with choices dependent on the user selected (i.e. if John Lennon is selected then choices are vocals, guitar, piano, synth, and harmonica; if Paul McCartney selected the choices will be bass, vocals, guitar, piano and drums etc.). I've been experimenting with Control Containers unsuccessfully and I'm wondering if I am not approaching this in the right way.  Any ideas?

if your second list box is dependent on the results from the users choice on the first list box, your only option (that I've found) is to do two workflows. The first workflow does the first list box, writes the results to a file/db somewhere, then the workflow launches the second workflow on completion and it gives you the second list box based on the first choice.

Agree with @rfoster7 , Alteryx is not a run-time supported applicaiton so we need to Chained Apps to do what you need.

@rfoster7 and @Qiu , thank you for your answers, I now see how to chain the apps, but I am not getting how to get the data for the 2nd List Box. I export data from first workflow after a choice is made, but I do not know to produce output suitable for use by second workflow as input for 2nd list box.
