How can I show my task list by due date?
Environment:
Event Temple Web App
Procedure:
Views are default sorted by date created, with the most recently created showing first. The sort order of the Task List (as well as other lists & reports) can be updated by clicking the relevant column heading (in this case, "Due At").
Clicking on the heading multiple times will allow you to change the sort order. In the example below, the Due Date has been selected and is sorted in chronological order from oldest to newest.
If this is the preference for your view, we recommend you Save View once you have made the necessary updates.
