1. Go to “slidebox” in the sidebar
2. Click on “+ New slidebox” on the top right of the page
3. Choose a name for your slidebox and click on “Create”.
4) Select the collections which you want to add to your slidebox and press “>”.
5) Return to the list, by using the “Back to slideboxes” button, or preview your newly created slidebox by clicking on “Preview” button.
