# Advanced Example
Elementor Core IntermediateFor a more advanced example we will create a widget with a repeater field, to allow the user to generate a list with items. It will also have a conditional field display when choosing "other" marker type, to display a new control that let's the user enter a custom marker (opens new window).
# Folder Structure
The addon will have two files. One file for the widget and a main file to register the widget.
elementor-list-widget/
