To show or hide completed matters, you will need to add the 'State' column to your matter list. To add the 'State' column, just look for the below-highlighted icon at the top right corner of your matter list.
A column selector will pop up, and you'll find the 'State' attribute near the top on the left - just drag it over to the top of the list on the right - then click Apply.
The column should now appear on your matter grid, and you can then click on the 'Filter' icon to choose which state(s) you want to view.
Choose the relevant options and click 'Filter'
