Totara Learn Open Discussions

Hi Kanaat

Third party plugins from Moodle are able to be used in Totara.

They are not supported or guaranteed to continue working with Totara but in general are expected to be compatible. There are more details on the compatibility here 

There are some standard blocks that can help course navigation (the navigation and section links blocks) 

There are some discussions on course navigation here with instructions on using a collapsible topic theme in Totara.

Regards
