To create a section template in HubSpot, two key components are mandatory. First, a template annotation with templateType: section is required. This annotation explicitly tells HubSpot that the file defines a reusable section, allowing it to be recognized and used within the drag-and-drop editor. Without this annotation, the file would not be registered as a section. Second, a dndsection tag is essential. This tag defines the editable area within the section template where content can be added or rearranged. The dndarea tag is used within modules or themes, not directly for defining a section template itself. A link to a CSS file is optional for styling but not a requirement for the fundamental creation of the section template.
