I used jQueryMobile1.3 and SimpleDialgue2 。I want to create a popup to input the sth . I used Blank Mode "Inlining" - Adoption.
In WebBrowser, It is OK. But in iPad or iPhone or any mobile device ,I input every letter ,it will be move down and create a blank space .Sometimes the keyboard will cover the dialogue box.I try to visit the input mode "http://dev.jtsage.com/jQM-SimpleDialog/demos2/button.html" .There is a same issue.
