Methods

To call below functions you need to get the instance of SumoSelect object which can be done as

 var MySelect;
$(document).ready(function () {
            MySelect = $('.SlectBox').SumoSelect();
     });

Or simply you can get the instance from select element directly i.e.

 var MySelect = $('select.SlectBox')[0].sumo;

Note : The SumoSelect object is directly binded with native select element not with the jquery object of element.

Following is the list of methods of SumoSelect.

• .unload()

  Deactivate the SumoSelect plugin and display original select element. ( You can reinitialize the SumoSelect for this select. )

   $('select.SlectBox')[0].sumo.unload();

• .add(value [,text][,index][,attrs])

  Insert an new item in the select at a given index if index is provided else added to last. use index 0 to insert at the begining.

  // adds a option with value and html set to 'india' at the last.
  $('select.SlectBox')[0].sumo.add('india');
  
  // adds a option with value and html set to 'india' at index no 3.
  $('select.SlectBox')[0].sumo.add('india',3);
  
  // adds a option with value = 'india' and html = 'Indian' at the last.
  $('select.SlectBox')[0].sumo.add('india','Indian');
  
  // adds a option with value and html set to 'india' at index no 0.
  $('select.SlectBox')[0].sumo.add('india','Indian',0);

  // adds a option with value and html set to 'india' at index no 0 with some attributes. $('select.SlectBox')[0].sumo.add('india','Indian',0, {'data-test': 'test'});
• .remove(index)

  Removes an item from a given index number.

   $('select.SlectBox')[0].sumo.remove(2);

• .selectItem(index/value)

  Selects (check an item) an item in the list by index or by its value. You can select multiple items in case of a multiselect.

  //selects the item at index 2
   $('select.SlectBox')[0].sumo.selectItem(2);
   //selects the item having value "volo"
   $('select.SlectBox')[0].sumo.selectItem('volo');

  //unselects the item at index 2
   $('select.SlectBox')[0].sumo.unSelectItem(2);
