Click on ‘Step 1, make your own filters’ in the overview after you have clicked on My checklist. Then select ‘new’ for creating a new filter. After creating a filter name, fill in the name of each label (each filter can consist of three levels).
Then fill in a pre-set filter value and press on the green ‘+’ button to add the value. Repeat this step, until all filter values of this main filter label are included. Don’t forget to add the last value by clicking the ‘+’ button.
If you would like to include sub(-sub)-filter values, press on the arrow next to a filter value. You can now enter the pre-set values of your sub-filters.
