    return (numSelected == 1) ? "{0} item selected" : "{0} items selected";
  },

  // text for max options
  maxOptionsText: function (numAll, numGroup) {
    return [
      (numAll == 1) ? 'Limit reached ({n} item max)' : 'Limit reached ({n} items max)',
      (numGroup == 1) ? 'Group limit reached ({n} item max)' : 'Group limit reached ({n} items max)'

  // auto reposition to fit screen
  dropupAuto: true,

  // adds a header to the dropdown select

var options = {
      ajax          : {
        url     : '/ajax',
        type    : 'POST',
        dataType: 'json',
        // Use "{{{q}}}" as a placeholder and Ajax Bootstrap Select will
        // automatically replace it with the value of the search query.
        data    : {
          q: '{{{q}}}'
        }
      },
      locale        : {
        emptyTitle: 'Select and Begin Typing'
      },
      log           : 3,
      preprocessData: function (data) {
        var i, l = data.length, array = [];
        if (l) {
          for (i = 0; i < l; i++) {
            array.push($.extend(true, data[i], {
              text : data[i].Name,
              value: data[i].Email,
              data : {
                subtext: data[i].Email
              }
            }));
          }
        }
        // You must always return a valid array when processing data. The
        // data argument passed is a clone and cannot be modified directly.
        return array;
      }
  };
  
$('.selectpicker').selectpicker().filter('.with-ajax').ajaxSelectPicker(options);
