and also you can use the calendar’s renderDayCell event to customize the appearance of the each day cell.

Below is the list of classes that provides flexible way to customize the DatePicker component.

Class Name Description

The following example disables the weekends of every month using renderDayCell event. Here we have used the e-disabled class to highlight the disabled date.

var datepicker = new ej.calendars.DatePicker({
        placeholder: 'Choose a date',
           // Bind the renderDayCell event to customize the each day cell.
    renderDayCell: onRenderCell,
    // sets the placeholder
    placeholder: 'Enter date',
    cssClass: 'e-custom-style'    
    });

 
function onRenderCell(args) {
    if (args.date.getDay() == 0 || args.date.getDay() == 6) {
        //sets isDisabled to true to disable the date.
        args.isDisabled = true;
        //To know about the disabled date customization, you can refer in "styles.css".
    }

}

    datepicker.appendTo('#element');

Adding mandatory asterisk to placeholder and float label

You can add a mandatory asterisk(*) to placeholder and float label using .e-input-group.e-control-wrapper.e-float-input .e-float-text::after class.

var month = new Date().getMonth();
   var fullYear = new Date().getFullYear();
   
   var datepicker = new ej.calendars.DatePicker({
        placeholder: 'Choose a date',
            // Sets the min.
    min: new Date(fullYear, month , 9),
    //Sets the max.
    max: new Date(fullYear, month, 15),
    // Sets the value.
    value: new Date(fullYear, month , 11)
    });
    datepicker.appendTo('#element');
