I have a text field in a Power Apps form with values separated by commas (e.g., John Doe, Joe Smith, Jane Doe, etc.). I want to use each value in the Items property of a dropdown so, when the use clicks the dropdown, they see each value as a separate item in the dropdown list. I assume this can be done, but I don't know how to parse the values so they display as separate items in the dropdown. Thank you in advance for your help.
