How to change datetime to yyyy-mm-dd h:s

i want to change datetime format with ‘yyyy-mm-dd h:s’

int date.extensions.js i changed mask: "1/2/y h:s", placeholder: "dd/mm/yyyy hh:mm", alias: "dd/mm/yyyy", to mask: "y-1-2 h:s", placeholder: "yyyy-mm-dd hh:mm", leapday: "-02-29", separator: "-", alias: "yyyy/mm/dd",

then input “2021-02-dd hh:mm”, the dd not works

@RobinHerbots “h:s” part is not editable in input field in your fiddle example. Could you hint how to fix that?

@denis-chmel @buttflattery I tried some examples and i got some configs that work with date and time validation. My fiddle: $('input').inputmask({ mask: "y-2-1 h:s", placeholder: "yyyy-mm-dd hh:mm", separator: "-", alias: "datetime" });
