To add courses to your bundle, go to 'Courses' > 'Bundles' > click 'Bundle' that has already been created or create a new bundle.
Next, click 'Contents'. Here, you can add courses to the bundle but they must be already published.
Go to the 'Add course to this bundle' box and click the 'arrows' on the right-hand side to open up a list of all the available courses to add to the bundle.
'Select' a course from the list that you want to add to a bundle, and then click 'Add Course'.
We added two courses so the content of this bundle can be found here:
