Hide Drop down list items across multiple pages.

Your description is not concrete enough to give you a solution you can plug in. Not sure exactly what you want to hide. It will be a lot easier to understand what you're doing if you attach a sample Excel file. See yellow banner at the top of the page.

Also welcome to the forum, but please do not populate your profile with jokes. We ask for location so we can understand what Excel localization you are using and possibly time zone for communication purposes. If you don't want to give your city, tell us the state/province, or at least the country.
