# Simple Example

Elementor Core Advanced

Let's build an addon that adds a new control to Elementor. The control will display a select field with the ability to choose currencies.

# Folder Structure

The addon will have three files. The main file will register the control and the JS file. To test the control we will create a simple test widget.

elementor-currency-control/
|
├─ controls/
|  └─ currency.php
|
├─ widgets/
|  └─ currency-widget.php
|
└─ elementor-currency-control.php
