Dear Asad Aslam,
I had the same requirement; you can solve this with some widgets in Marketplace.
Let me tell you how you can solve this problem with the default filters.
Hope my answer helps, reach me out for any queries.
Hi Asad Aslam,
Dou you want to change the date picker UI or Just Date Showing in Date box in frontend?
If you want to change in date selection i.e., DatePicker then you have to look for some marketplace widgets like Mendix Marketplace - Month and Year Picker
Or if you want to just show the year in the date input widget box, then you can use Date Format section and can select the format in which you have to view in frontend.
