The Drag & Drop editor Layouts page in the Setup module of Spotler MailPro is designed for managing template layouts. This page is only accessed to insert a small piece of code required for templates to function properly. Spotler handles this process for you.
The layout itself is a simple table that creates space for content blocks. When creating a new template, a layout is generated, and its layout ID is placed in the template under data-layout-type, as shown here:
Please note: Preferably do not edit your own layout
Creating and managing your own templates requires knowledge of HTML, Twig, and CSS. Spotler's support team does not provide assistance for custom templates. Additionally, backups of templates and blocks are not typically maintained, so proceed with caution when making changes.
