You can use an incognito window or a different browser to isolate the issue where you can't see any of your drop-down menus. This method helps eliminate temporary files, saved data, or extensions that may be causing the issue.
If the issue persists, contact our QuickBooks Online Live Support team. They can look into your situation closely and provide specific suggestions to resolve problems with your drop-down menus.
Feel free to post in the Community if you need further assistance. We'd be glad to help.
