Why is my choice column not showing in my PowerApps Portal

You may notice that your choice column is not showing on your Basic Web Form or an Advanced Web Form in your PowerApps Portal. Well the answer is that Multi Choice columns are not supporting in PowerApps Portals (at present).

One way to get around this is provide a number of single choice drop down columns to replicate the same functionality. This may not be as tidy as how your can add a Multi-Choice column in PowerApps Canvas Apps, but it does function as a workaround in the meantime.
