Customer Self Service Portal - Subject column rendering

[dokane]

The Subject column on the Case table renders as a very long drop down list on the Portal.

I know this derives from Subject on the Customer Service Hub but it isn't pretty for the logged in portal user to scroll through to find their subject. D365 side it has a nice filter down tree like structure.

From what I see it is a Lookup control in the Portal so I could go down the road of creating a custom Parent field and attempting to filter Subject based on the selection of the custom field.

Has anyone come across this Subject field before on the Portal and come up with a way to make it more usable for the portal user?

Believe it or not, I already had the article in my clipboard as I used for another thread: Custom Lookup filtering on PowerApps Portals - Dancing with CRM

this article is going a bit beyond, because it's performing a query and then filtering the dropdown.. but you might need to find another criteria to decide which values to show or not.
