No Twig or HTML properties
By default if a custom component doesn’t use a template or html property, it will use the default twig that Site Studio provides. This default template will render a `<div>` that has a class of the id of the custom component. All field values will be accessible via a data attribute on that div `data-ssa-custom-component` and stored as a JSON object.
If the custom component contains any dropzone, each one of them will be rendered in a `<template>` inside the div and can be retrieved by a data attribute `data-dropzone-id` where the value will be `dropzone-[uuid-of-the-dropzone]`. You can find the uuid of a dropzone in the `canvas` object of the custom component form Json.
