If you are building many single lessons or one-off courses in your eLearnCommerce, you will want to have a simple and effective way of showing related courses in the same category on your right-hand column.
This will allow your students to see many of the courses that are directly related to the material they are currently using.
To achieve this, you will need a Dynamic Sidebar Widget.
This is an example of such a widget, with a helpful video, but as always, we suggest you do your research to find the perfect one for your needs.
Once you have your Dynamic Sidebar Widget configured just the way you want it, it is easy to add to your right-hand columns of your WP site.
From your WP Menu > Appearance > Widgets
then select your chosen widget and decide where you want it to appear.
Having highly relevant, highly targeted offers to your current students is the best way to ensure you are offering them exactly what they need when they need it.
