# Complex Example
Elementor Core AdvancedNow we'll build an addon that adds a new control to Elementor by using an external library. The control will display a textarea field, and we will use the Emoji One Area (opens new window) library to allow the user to add emojis to the content.
# Folder Structure
The addon will have four files. The main file will register the control and the JS file. To test the control we will create a simple test widget.
