Sumoselect raise some very helpful events on which you can hook your custom handlers.

$('select.SlectBox').on('sumo:opened', function(sumo) {
    // Do stuff here
    console.log("Drop down opened", sumo)

Available events

// Drop down initialized.
// Drop down opening
// Drop down opened
// Drop down closing
// Drop down closed.
// Drop down unloaded.


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. )

  • .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.
    // adds a option with value and html set to 'india' at index no 3.
    // adds a option with value = 'india' and html = 'Indian' at the last.
    // adds a option with value and html set to 'india' at index no 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.

  • .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
     //selects the item having value "volo"
  • .unSelectItem(index/value)

    unselect (uncheck an item) an item in list by index or by value

    //unselects the item at index 2
     //unselects the item having value "volvo"
  • .disableItem(index)

    Disables and item in the list

    //disables the item at index 2
  • .enableItem(index)

    Enables and item in the list

    //enables the item at index 2
  • .selectAll()

    Selects all items list

    //selects all items (excluding disabled)
  • .unSelectAll()

    Un selects all items in the list

    //Un select all items
  • .enable()

    Enables the SumoSelect control

  • .disable()

    Disable the SumoSelect control

  • .reload()

    This method reloads the UI over original select element. so now you can perform the desired operations on underlying select element and then update the UI od sumoselct after that.

    //Reloads the UI of plugin.

*** You can add custom css class to options (css class added to option is added to the generated li.)
