Populating a Lookup column that is configured to "Allow multiple values" in Nintex Workflow cloud

@Haywhy21  Are you referring to a data lookup control on a NWC Form?

Yes @leighburke. I will appreciate your help 

@Haywhy21 Multi select is currently not supported in a lookup control. You could add the lookup control into a repeating section(https://help.nintex.com/en-US/nwc/Content/Designer/FormControls/Repeatingsection.htm), this would allow them to select an option multiple times. You should also request this feature on the uservoice(https://uservoice.nintex.com), if you would like it added.

@leighburke thank you, I appreciate your kind gesture.
