Why does my dropdown menu work OK on my PC but NOT on my ipad. It shows for second and then disappears soooo I cannot touch a dropdown option to bring up the page I want.

Your Windows PC and iPad will be using different web browsers. If you are experiencing difficulties with iPadOS Safari - and you are unable to resolve the problem through refining Safari’s settings- try using a different browser, such as Firefox or Chrome.

You would be best advised to seek assistance from WIX technical support - as they will be best placed to help you with ensuring that your website is compatible with all browsers (including those based upon WebKit - as used by Apple devices).
