I played with the data-options
field and found out that using only one theme and disabling animation made the element much faster even on PC. At least I could see the difference on my fast PC. So, on tablet the difference may be even bigger.
Here is the data-options
when changed:
"mode":"datebox", "useFocus": true, "useNewStyle":true, "useAnimation" : false, "themeHeader": "b", "themeButton": "b", "themeInput": "b"
So, there all theme related is with b
and the useanimation
thing is new.
