With the release of Dynamics 365 v9.0, Microsoft introduced a new data type – Multi-Select Option Set. With the help of this new data type, we can select more than one option set in Dynamics 365.

The Power Apps Portal/Dynamics Portal does not support multi-select option field types out-of-the-box on Entity Forms and Web Forms. The work around is to create a dummy multi-select option set field in Entity Forms and Web Forms at whichever places you want to use. With some amount coding, you can demonstrate a particular pattern that can be used to add sophisticated UI elements to your Portal.

In this blog we will show how to display Multi-Select Option Set Field on Portal Apps and how to set Multi-Select Option Set value in Microsoft Dynamics CRM from Portal.

  • Create a text-field in CRM for portal internal use.
  • Add that created field into entity form and hide that field on entity form.
