How to make use of it:

1. Attach the emoji picker button to your input field.

<input id="example" type="text" />
<button id="picker">Emoji Picker</button>

2. Load the EmojiButtonList.js JavaScript library.

<link rel="stylesheet" href="src/emojibuttonlistjs.min.css" />
<script src="src/emojibuttonlistjs.min.js"></script>

3. Initialize the emoji picker button.

instance = new emojiButtonList( "picker", {
  textBoxID: "example"
})

4. Config the emoji picker with the next parameters:

instance = new emojiButtonList( "picker", {
  dropDownXAlign: "left",
  dropDownYAlign: "bottom"
  yAlignMargin: 0,
  xAlignMargin: 0,
  emojiRangesToShow: []
})

5. Trigger a function after an emoji has been chosen.

instance = new emojiButtonList( "picker", { 
  onEmojiClick: function(emojiText) {
    // do something
  }
})
