Filter topics

What do you want to do?

 

Filtering is a convenient way to view only a subset of the topics on your map. This eliminates the need to delete topics that are not currently of interest, but remain valid map content.

Filtering effects how the map is displayed in Map view, Outline view, Linked Maps view and Walk Through view. By default, the filter is also applied to the Gantt Chart view, but you can choose to show all the tasks on your map in the Gantt Chart without regard to the filter.

There are four ways to filter your map:

  1. Show branch alone: select a topic and then use this command to show the branch only, (the selected topic and its subtopics) without the central topic, parents or siblings.
  2. Direct filtering:  select a set of topics and then use the Show or Hide commands to show or hide those topics.
  3. Use instant Task Filters: these are shown in the Show or Hide pull-down menus, and allow you to filter the map's topics based on specific task conditions.
  4. Use Power Filters: available from the Show or Hide pull-down menu, this command lets you specify the filter criteria (including a variety of properties and text) to use.

Filtering is cumulative. Topics that are already hidden remain hidden when you apply a new filter. You must remove any filter you've previously applied to apply a new filter to all the map topics. The filter indicator is displayed at lower-left, and the  Remove Filter command (on the View tab, and in the Filter group) is active when a filter is active.

When the map is saved, it is saved in a filtered state. All topics are still in the map, but hidden topics are not visible until you remove the filter. You can save a copy of the filtered map - topics hidden by the filter are not included in the new copy of the map.

Show a branch alone

You can show a branch by itself  to focus attention on a specific topic. This is especially useful for presenting larger maps in meetings, to enable the viewer to see the topic's details without being distracted by the rest of the map.

The Show Branch Alone command shows only the selected topic and its descendants.

  1. Select a topic.
  2. On the View tab, in the Filter group, click the Branch pull down and select Show Branch Alone.

The filter indicator displays at lower left

Show topics one level higher

  1. On the View tab, in the Filter group, click the Branch pull down.
  2. Click Show One Level Up.

You can continue to reveal levels in this way until you reach the map's central topic.

Show all topics

To see the hidden parent topics again, do one of the following:

Filter topics directly

You can filter topics directly by selecting topics to show or hide, or by selecting a single topic to display, along with all its descendants. To filter topics based on their properties use the Power Filter option.

Show or hide a set of topics

  1. Select the set of topics or elements on the map.
  1. On the View tab, in the Filter group, click Show or Hide.

Show shows only those topics that are selected (hides all those that are not selected)

Hide shows only those topics not selected (hides all those that are selected)

Filtering is cumulative. If you add more topics to the map, or you want to further refine your view of the map, you can filter the remaining visible topics.

Use instant Task Filters

Task Filters provide a convenient way to see tasks that meet specific criteria. You do not need to select a topic to use these filters - they filter all the topics on the map.

  1. On the View tab, in the Filter group, click the Show or Hide pull-down.
  2. Click the Task Filter you want to use.

Topics that match the filter criteria will be shown or hidden.

Filter topics by properties and text

The Power Filter command lets you filter a set of topics based on a query to match the properties you specify by selecting match criteria. You can choose to:

Show only those topics that match the criteria (hides non-matching topics)

Hide topics that match the criteria (shows only non-matching topics).
