How do I create a new category set?

To create a new category set, you must first navigate to the appropriate page. To do so, click on Templates -> Category Sets in the left navigation. You will now see an overview with all your existing category sets. Now click on the button "Create new category set" in the upper right corner. In the pop-up that appears, enter a name for the category set and then click "Save". Now a new pop-up will open where you will see a searchable list of all your categories on the left and the categories assigned to your category set on the right. Since you are creating a new set, this list is empty at the moment. You can add a category to your set by checking the checkbox for the appropriate category on the left. When you have added your desired categories, don't forget to click the "Save" button.
