Disable Year from Date-Time Picker

To disable the year option in the date-time picker, override the "openDateTimePicker" command. Doing so, you can remove the HTML element for the year option and disable it. See the following code for an example:

let openDateTimePickerCommand = GC.Spread.Sheets.Commands.openDateTimePicker; let oldExecute = openDateTimePickerCommand.execute; openDateTimePickerCommand.execute = function () { let result = oldExecute.apply(this, arguments); let elements = document.querySelectorAll('.gc-year-select-div'); elements.forEach((element) => { element.classList.add('disable-div'); }); return result; }

You can similarly disable other HTML elements this way.
