Please find the sample which prepared for your issue - https://www.syncfusion.com/downloads/support/forum/167597/ze/ChangeDropdownData1598242472

    <ejs-datepicker id="Tab_DatePicker" width="200" change="onChange" cssClass="DatePicker" placeholder="Enter date"></ejs-datepicker> 

</div> 

  

<script> 

    function onChange(args) { 

        if (args.value.getMonth() == 6) { 

            var dropdownObj = document.getElementById("ej2_dropdownlist_0").ej2_instances[0]; 

            var dropdownObj1 = document.getElementById("ej2_dropdownlist_1").ej2_instances[0];

            var dropdownObj4 = document.getElementById("ej2_dropdownlist_4").ej2_instances[0]; 

            var dataSource = ["Badminton", "Cricket", "Football", "Golf", "Tennis"]; 

            dropdownObj.dataSource = dataSource; 

            dropdownObj1.dataSource = dataSource; 

            dropdownObj2.dataSource = dataSource;
