Hi @bala_1312,

To make field mandatory in widget, need to use html attributes required 

<input type="text" id="username" name="username" required>

Hi @Mohan raj ,

It should be dependent on dropdown field , it should not be mandatory by default .

Hello@debo jyoti ,  you can use the OnChange client script.

function DropdownChange() {

    var dropdownValue = g_form.getValue('myDropdownName');

    var textField =g_form.getValue('myInputFieldName');

    if (dropdownValue === 'someValueYouWant') {

        textField.required = true;

    } else {

        textField.required = false;

    }

}

If my response helped please mark it correct and close the thread so that it benefits future readers.
