Callbacks

interface Callback {
  onBeforeOpen: (( arg: string | Array<string>) => boolean) | null;
  onBeforeClose: (( arg: string | Array<string>) => boolean) | null;
  onBeforeChange: (( arg: string) => boolean) | null;
  onOpen: (() => void) | null;
  onClose: (() => void) | null;
  onChange: (() => void) | null;
  onFocus: (() => void) | null;
  onBlur: (() => void) | null;
  onKeyDown: (() => void) | null;
  onKeyUp: (() => void) | null;
  onKeyPress: (() => void) | null;
  onMenuScrollTop: (() => void) | null;
  onMenuScrollEnd: (() => void) | null;
}

options.callback = {
  onBeforeOpen: null,
  onOpen: null,
  onBeforeClose: null,
  onClose: null,
  onBeforeChange: null,
  onChange: null,
  onFocus: null,
  onBlur: null,
  // keyboard
  onKeyDown: null, //*
  onKeyUp: null, //*
  onKeyPress: null, //*
}

// Note: on `onBeforeOpen`, `onBeforeClose`, and `onBeforeChange` 
// it is possible to return false to prevent next action.

// Example:

options.callback.onBeforeOpen = function (currentValue) {
  if (currentValue === 'something') {
    return false; // it will prevent next step
  }
  // do something
}

/**
 
  `focus`: on focus select element
  `blur`: on blur select element

// Example: 
const events = selectInstance.Events;
events.addEventListener("open", () => {

Methods

const selectInstance = SelectV2(element, options);

// using select.methods
const {

    focus,
    blur,
    select,
    clearByIndex,
    clear,
