Hi there,
Thanks for reaching out.
Yes, it is possible to customize the layout of individual class/course pages in the SP LMS Courses component using Joomla template overrides, which is the recommended and update-safe approach.
However, the override must match the exact structure used by the component.
Create your overrides here:
/templates/your_template/html/com_splms/
Then you must replicate the exact view structure from the component, for example:
From:
/components/com_splms/views/course/tmpl/default.php
To:
/templates/your_template/html/com_splms/course/default.php
Best regards,
