Display or Hide Summary Tasks

First of all, if you ever find yourself wanting to hide summary tasks in your project and focus solely on the detailed tasks and milestones, here’s what you do:

  • Click the Gantt “Chart Format” ribbon tab to display the Gantt Chart Format ribbon with various formatting options.
  • On the far right end of the ribbon, DESELECT the “Summary Tasks” checkbox in the “Show/Hide” section.

Voila! Now, your task list only includes detailed tasks and milestones. To bring back the hidden summary tasks, simply select the “Summary Tasks” checkbox again. Now, that wasn’t so hard, was it?

Display or Hide Outline Numbers

Next, let’s talk about outline numbers. Keep in mind that Microsoft Project automatically calculates an Outline Number value for every task in your project, but those values are hidden by default. Sometimes, you might want to see those outline numbers. Here’s how you can do that:

  1. Again, navigate to the “Gantt Chart Format” ribbon.
  2. In the “Show/Hide” section of the ribbon, SELECT the “Outline Number” checkbox.

You’ll notice that Microsoft Project automatically calculates an Outline Number value for each task in your project. It’s a handy way to organize and visualize your tasks. For example, your tasks might be numbered as 1, 1.1, 1.1.1, and so on. And if you decide you don’t need the outline numbers cluttering up your view, simply deselect the “Outline Number” checkbox, and they’ll vanish.

That’s it! Now you know how to display or hide summary tasks and outline numbers in Microsoft Project. If you have questions, please add them in the “Leave a Reply” section below.
