Hello,

I am experiencing an issue with the accordion (course topics/lessons) in SP LMS.

The accordion works correctly in Firefox, but it does not expand in Chrome or Edge. After checking the browser console, I found the following error:

Uncaught TypeError: COLLAPSE: Option "parent" provided type "string" but expected type "(null|element)"

This error appears to be related to Bootstrap 5.3.8. It seems that SP LMS is initializing the Collapse component using the "parent" option as a string (e.g. "#accordion"), while Bootstrap 5.3 requires a DOM element instead.

Because of this, the accordion fails to initialize properly in Chromium-based browsers.

My environment:

• Joomla version: 5.4.5.1
• SP LMS version: Last Available
• Template: Edulif but not working in no one
• Bootstrap version: 5.3.8

From my understanding, this could be fixed by converting the "parent" option to a DOM element (e.g. document.querySelector(...)) or by using the data-bs-parent attribute properly without conflicting JS initialization.

Could you please confirm if this is a known issue and provide a fix or update?

Thank you in advance.
