Hi @Anonymous ,
Do you want to use Multiple Option Set in portal?
Unfortunately, as what you said, PowerApps Portal doesn’t yet support multiselect option sets, so the field doesn’t show up on the Portal.
Here's a solution to solve this:
The first step is to add another field that is supported on the Portal – a text field. We’ll use this field to save the user’s selection back to Dynamics.
Next, we’ll need some custom JavaScript. This script will:
- Hide the text field.
- Add a multiselect HTML field where the text field was previously. This multiselect field will have options with values that correspond to the multiselect in Dynamics.
- Anytime the multiselect field changes, a comma delimited list of the selected options is stored in the hidden text field.
Here are docs about this in details for your reference:
