//initialize with previously sorted options
//By passing the previously sorted value taken from select2, in the form
//of an array of the previously selected options' values, the select2
//options will be ordered with the selected options sorted as they were
//before.

//Example:
previouslySortedOptions = ["3", "1", "2"];

//Initialize with ARRAY of previously sorted options.
$(select2multiselect).select2Sortable(previouslySortedOptions);

//with other config options, specify "data:previouslySortedOptions" as previously selected info
    $(select2multiselect).select2Sortable({
    bindOrder: 'formSubmit' // or `sortableStop`,
    sortableOptions: {
        // please refer to jQuery UI sortable API (http://api.jqueryui.com/sortable/)
    },
    select2Options:{ //give select2 config options as well.
        // please refer to select2 documentation (https://select2.github.io/)
    },
    data:previouslySortedOptions
});

//perform sorting after initialization
$(select2multiselect).select2SortableOrder(previouslySortedOptions );
