SharePoint MultiChoice with ‘Fill-in’ choices

Power Apps forms is an excellent tool to connect and customize SharePoint list forms, but when they include a MultiChoice Field, is only provided a combobox where its not possible to use the feature of ‘Fill-in’ choices of the field.

When you add an edit-form, and connect it to the Sharepoint listPower Apps creates a combo-box for the multichoice field where you can add multiple values but can’t add custom choices

But here is a easy and pretty alternative!
This component, will allow you to easily manage the sharePoint multichoice fields with the ‘Fill-in’ choices in a Power Apps list form. Just import and configure as explained bellow.

Press Upload File and select the file you downloaded.

Config Component

In the Power Apps, add to a screen the edit form connected to the list.
