jQuery datepicker: Convert select dropdown into ul

I am using the jquery-ui datepicker component however the

month
and
year
dropdowns are
select
tags.

I need to style them in ways that are not possible with select elements so I would like to convert them to
ul
elements.

Any help would be appreciated - here is a starter jsFiddle with the jquery-ui datepicker https://jsfiddle.net/GeekOnGadgets/wra3pcsv/

Answer

The following code may help you. You can see the result in this jsFiddle.

// Replace a select element by a ul element
var convertToList = function (inst, className) {
    var $selectElement = inst.dpDiv.find('.' + className);
    var $listElement = $('<ul class="{0} dateList"></ul>'.replace('{0}', className + '-list')).appendTo($selectElement.parent());
    $selectElement.children(' option').each(function () {
        // Replace each option of the select element by a li element
        $listElement.append('<li class="dateListItem" value="{0}">{1}</li>'.replace('{0}', $(this).val()).replace('{1}', $(this).text()));
    });
    $listElement.find('.dateListItem').click(function () {
        // When an item is clicked, set the corresponding value in
        // the original select element and trigger the change event
        $selectElement.val($(this).val());
        $selectElement.change();
    }).each(function () {
        // Add the selectedValue class to the selected item
        if ($(this).val() == $selectElement.val()) {
            $(this).addClass('selectedValue');
        }
    });
};

// Replace the month and year select elements
var convertToDatePickerWithLists = function (inst) {
    setTimeout(function () {
        inst.dpDiv.addClass('datePickerWithLists');
        convertToList(inst, 'ui-datepicker-month');
        convertToList(inst, 'ui-datepicker-year');
    }, 0);
};

// Associate the datepicker to the text input element
$("#datepicker").datepicker({
    changeMonth: true,
    changeYear: true,
    beforeShow: function (input, inst) {
        // Modify the datepicker when it is initially displayed
        convertToDatePickerWithLists(inst);
    },
    onChangeMonthYear: function (year, month, inst) {
        // Modify the datepicker every time the month/year is changed
        convertToDatePickerWithLists(inst);
    }
});

Here are the CSS styles for the various classes:

.datePickerWithLists .ui-datepicker-year,
.datePickerWithLists .ui-datepicker-month
{
    display: none; /* Hide the original select elements */
}

.datePickerWithLists .ui-datepicker-header
{
    height: 20em;
    background: #D0D0D0;
}

.dateList
{
    display: inline-block;
    list-style: none;
    font-size: 12px;
    vertical-align: top;
    margin: 0px;
    padding: 8px 0px 0px 0px;
    text-align: center;
    width: 40%;
}

.dateListItem
{
    line-height: 1.4em;
    cursor: pointer;
}

.dateListItem.selectedValue
{
    background-color: black;
    color: white;
}

After discussing the specific needs of GeekOnGadgets, the code and style has been adapted as shown in this jsfiddle.
