You can add resource groups in configuration. This is useful if you have many resources and the planning work is divided based on different kind of resources or you like to have your planning board divided by resource.
Go to Configuration > Order input
Click on Resource groups
Click on Add resource group.
Once you click on Add resource group, you can now enter the details of that group, e.g.
Name of the resource group.
If the resource active/inactive.
What are the resources in that group.
Once saved, you will see that your planning board is divided in those categories and that you can filter on these groups on your planning board.
If you don't want to see the resource group, you'll have the option to turn the toggle off in the 'Customize' section.
