I am currently shifting lot of html form fields(radio button, timefield, textfield.. etc) into extjs based form fields mainly because I am using extjs layout and to make the look consistent. Also there seems few extra feature I don't need to reinvent.
But these days specially since html5/css3 is moving forward and lot of features are embedded into html5 tags and css3, started to wonder any benefit of using extjs form field anymore..
Don't get me wrong.. I am happy with extjs. I was just posting to get more wide opinions for the direction of web application we are developing to back me up as well.
But more I look into html5 (which is supported by most modern browser and will be to most other browser), I can see that native form field will be more fully supported..
Anyways.. considering you are a forum manager.. that is pretty biased
.. still my gut feeling is that it is not enough reason not to move toward html5/css3 considering new IE browser support quite fully for html5..
Lot says even older browser such as IE6, degardes gracefully.
Wonder that extjs developers would have any plan to move from customized ext form field (ie. datefield) to use html5 input type="date", "time".. etc.
