Any reason you're still using classic? and not the updated jQuery version - where I imagine the colour would be more easily configurable?
I have a date field and user need to pick the date so by default I went to classic date picker. I have no idea of updated jQuery version for date picker. Please let me know how to implement jquery date picker
Thanks in advance
"Date Picker (Classic)" is the v3.x date picker, which uses a popup window
"Date Picker" is the v4.x date picker, using jQuery to render it's content and does not launch a separate window. It also has more declarative settings available.
