Thank you @CODE-NINJA I’m reading it and somehow its similar in a way he puts the input values on his collection.
I was assuming that since it’s Wix’s datepicker element, it should automatically be the date format on the CMS collection when the data type “Date” is used. Coding it on the front-end to save the datepicker selected value to the CMS should not be the issue.
I’ll get back to you after reading your link and will try to do some tricks and I hope it works.
