Hi community
I applied the approach in Nick Hayduck's post to achieve the multiselect-option-set and got that working fine.
Nick Hayduck's post for reference: https://www.engineeredcode.com/blog/powerapps-portals-multiselect-option-set
Near the end of the post, it mentions alternate ways to prevent hard-coding the 'options'.
"Another option would be to use a global option set for your multiselect option set, and create another dummy regular option set field that you could add to your form that you could use to populate the possible values."
I have created the 'regular' option set field as suggested, but am not able to get its options onto the multiselect field.
Has anyone achieved this workaround?
