**You are going to want a plugin that you can modify. Use a glossary for example. Set the Moodle theme to Boost Create a course and enter the course. Create a glossary in the course and go to the glossary you just created Modify the implementation of the function glossary_extend_navigation to the following function glossary_extend_navigation($navigation, $course, $module, $cm) { $node = $navigation->create( 'This is a test for MDL-60653' , 'http://test.test' , \navigation_node::TYPE_CUSTOM, null , 0 ); $node->showinflatnavigation = true ; $navigation->add_node($node); } # Visit the glossary you created at step 3 Verify  that the node shows up in the flat navigation menu of Boost. Verify that the node is not indented. It should look like after.png and not like before.png.
