Hi TO_318,
I’m glad to be here and provide my assistance.
Per your creating steps, they are totally correct. I can also create a Drop-Down-List at my end. However, you mentioned that after you add the properties Content Control properties, they won’t display in this Drop-Down-List. I test it at my end but didn’t encounter with this issue.
If you are having this situation, can you provide screenshot about your issue to help us understand? Meantime, we suggest you try these steps to narrow down this issue.
- Run Word safe mode to avoid add-ins effects.
- Create a new document and follow these steps again.
- Update your Word. Go to File-> Account-> Update Options-> Update Now.
- Try to Online Repair Office, it will fix some issue. (Type Apps&Features in search bar-> Office-> Modify-> Online Repair)
If the issue still persists after trying these, we want to collect more information about this issue:
- Can you take a full screenshot about Word Product Information page? (Word-> File-> Account-> Product Information). We need to determine which version has this issue.
- When did this issue happened? Have you changed something? Like update?
- Does this issue happen to all documents or just one document?
- Can you edit other Content Controls by clicking Properties?
Regards,
Ivy
