How to create categories?
Step 1. Click on the icon to go to datasheet settings (only accessible by administrators)
Step 2. In the "Categories" section, you can either choose to create a new category (2a. on the picture below) or to edit an existing one (2b.)
Step 3. Either way, you can edit / type in the title, the order in which the categories will be displayed, the icon and its color which will display in the list of items. Categories that are not in use can be desactivated.
Step 4. Save the settings.
