Multiple Choice values from SharePoint list

This of for a NWC Form. I have a SharePoint list of individuals that need to notified by phone for a specific event.  What I would like to do is bring in the names of these individuals that are in the SharePoint list column to be listed in a Multiple Choice Type action on a form. So you can check them off as you contact them.

The column in sharpeoint would is just a short text field. I would like to use the multiple choice drop down or a label with a Yes/No box in front of it to display each person we need to contact. 

Wow! This is so much easier to build using O365 Form with List Lookups. 
Kind of struggling with NWC, haha!

SPO List - Event (Text Short), Contacts (Text Short)
This will be our lookup list. 

0365 Form

Events field setting

List Lookup (Event)

Contacts field setting

Notes - Text Long. Using Form rules to populate

Formula: replace( parseLookup([Form].[Contacts]), "," , "\n") 

Output
Just using “[Form].[Contacts]” 

Output (Final)

Use parseLookup function to clean up Lookup result.
Use replace function to replace comma with line break (“\n”)

PS - I haven’t figured out how to accomplish this with NWC form, yet

Hi @Andrew87 @Garrett 

Currently the only way to do this OOB with NAC forms would be to place the lookup inside of a repeating section, sadly we cannot rely on the nice and helpful APIs of sharepoint for this lookup.

HOWEVER forms plugins are now a thing and building a multiple select for this is actually possible now and I can make one, I will try put one together for you and share this with you as soon as it is ready.

Kind regards

Jake.
