```
var options = $('#mobility-table').find('select.MobilityCountry[data="'+selectionId+'"]').data('options').filter('[data="' + id + '"]');

    options.sort(function(a,b) {
        if (a.innerHTML > b.innerHTML) return 1;
        else if (a.innerHTML < b.innerHTML) return -1;
        else return 0;

```

The above code will give me all the list of cities upon selecting a country. I would like to add a default value 'All' at the first place in the variable 'options'. Can any one suggest me how to add this. Any help greatly appreciated. Thankyou.

Ex: options should have 'All,London,Scotland,Stanmore, Watford'.
