How to enable the past dates of jQuery inline datePicker?

You need to make sure that the minDate option is null.

$( "#from" ).datepicker({
    defaultDate: "-6m",
    buttonImageOnly: true,
    dateFormat: "d MM y",
    changeMonth: true,
    changeYear: true,
    numberOfMonths: 3,
    onSelect: function( selectedDate ) {
        $( "#from" ).datepicker( "option", "minDate", null );
    }
});
