Hello,

Recently I've encountered this problem with Drop Down Lists:

And when I start the app and try to choose from Drop Down List it displays only blank space...

If anybody knows what to do, please advise.

Hi @Anonymous,

I have made a test on my side, and don't have the issue that you mentioned. The screenshot as below:

Please take a try to modify the formula within the Items property of the Combo Box as below:

Choices(PDCA.KAT)

then check if the issue is solved.

In addition, please also check if you have renamed the corresponding columns within your PDCA list. If yes, please take a try to re-create a new app based on the PDCA list, check if the issue still exists.

Please also consider take a try to delete the connection to your PDCA list, then re-add a new connection to the it, check if the issue is solved.

Best regards,

Kris

Thank you for your reply.

I've already tried everything you mentioned, but with no avail.
I solved this problem by recreating PDCA list in Sharepoint (as another sharepoint list) and I've connected it to the Data Source.
Now everything works as if nothing happened, but unfortunately I still don't know what the source of the problem was.

I have an issue to get SharePoint Meta Data Column values. Could you clarify more on the default drop down combo is there any customization on the properties to show the meta data as in my case it can't be retrieved in the drop down and I got error ''the function choices has some invalid arguments".

I think this is actually a bug. The same thing happens to me and if I just cancel and rewrite the same function Choices() it will work fine. It is very annoing because this error keeps appearing and I still haven't found an explanaition.

Thanks, It works fine after recreating the SharePoint list.
But I have another issue, The issue is the drop down list does not show more than 20 meta data term items.
Is there any work arround to show all meta data terms.
