jQuery UI Datepicker v3.4.3 => Date range + Restricting

Hi,

When I want to use the both functionalities (Date range + Restricting), it becomes possible to have the date of end 'before' the date of begin (because the dates before the date of begin aren't grey...)

This is my script :

<script type="text/javascript" charset="utf-8">

$('#dateinput').datepicker({

rangeSelect: true,

minDate: '6w',

maxDate: '2y',

numberOfMonths: [2, 3],

stepMonths: 3, prevText: '<< Mois précédents',

nextText: 'Mois suivants >>'

});

</script>

Thanks & Have a nice day,

Emilie
