I am adding one extended attribute in the form of date field, and I wanted to add date picker in my page as html 5 date picker is not compatible in ie11. Please suggest
You are free to you any method you'd like for collecting dates via a widget - not limited to HTML 5 features.
Version 8.x includes a jQuery plugin called glowDateTimeSelector to assist with collecting dates. I'd probably start with that. But again, this is only one of many options available to you.
I have posted one question, can you guide me on that.
