I reported this to Cordoba below:
https://issues.apache.org/jira/browse/CB-13287
There was an error in Apple UIWebViewthat cordova uses for iOS. I worked with one of our iOS developers to create a sample native iOS application using only Swift(no Cordova). A dropdown problem was also present there.
Apple seems to have another view called WKWebView, which seems to be preferable since iOS 8.0. The following is a quote from Apple's WKWebView documentation . I confirmed that there is no problem with the dropdown in WKWebView.
