In this example, custom templates are loaded. These templates are stored in templates/default_templates_with_naphtalane.json (URL is relative to the directory of Marvin JS package).
To display them on custom template toolbar, define the location of their source file in the data-templateurl attribute of the iframe tag of the editor.
<div class="resizable">
<iframe src="../editorws.html" id="sketch" class="sketcher-frame" data-templateurl="templates/default_templates_with_naphtalane.json"></iframe>
</div>
