Been building a new form with Expression Engine 2.9.2, however when trying to use the datepicker, it seems to be using a very old version of JQuery UI, so old that it only actually functions at all in Chrome.
Both Firefox and IE (latest and older versions I've tested) don't actually get a working date-picker at all, they literally get no field. I've tried using it as a date field, a text field and several classes the datepicker is mean to pick up (datepicker, hasDatepicker).
Looking at it, this seems be a very old version of JQuery UI from several years ago which explains why it doesn't function, however when I download the latest version, the file layout and names are all completely different so its not just a simple matter of replacing the files with the more up to date versions.
So, is there a relatively simple way to update the version of JQuery UI that EE use or is it easier to just disable the EE built-in datepicker and use an external one to do the same job?
I'm also curious as to why EE would be using such an old version of JQuery UI?
