Custom Component (widget) development

You can easily develop the UI for such scheduling component, but Lithium is probably not the best platform for the data storage backend. I am not aware if an easy way to add new data fields into the Lithium database that would allow you to store the appointment information you are creating in your scheduling component.
once you have an external database that you can access via a RESTful API it's as easy as following the documentation on writing custom components: http://lithosphere.lithium.com/t5/Developers-Knowledge-Base/Advance-Studio-Documentation-Part-3-Custom-Content-vs-Custom/ta-p/64552

Thanks, I will try this.
