To make a grouping, you must first activate the advanced mode. To do this, click on the button with the three vertically arranged dots at the top right. In the menu that appears, you can activate the advanced mode.

Now drag the column in the task list by which you want to group the tasks into the area on the left above the table. Now you can filter within this grouping and sort in ascending or descending order.

If you want to group by a column that is not yet displayed in the view, first show the column selection by clicking on the button with the three vertically arranged dots in the upper right corner and then on Select columns. Now drag the desired column from the menu to the top left.

You can also group by multiple columns.

To filter within the grouping, click on the filter icon in the column dragged up and select the filter criterion.

Example: If you group by people and now want to filter by a specific employee, first drag the Contacts column up, then click the filter icon and select the desired person from the drop-down menu.

To sort alphabetically ascending or descending within the grouping, click on the arrow in the column you dragged up:

Example: If you want to sort all grouped contacts alphabetically ascending, click on the arrow so that it points upwards.
