Each map starts out with a built-in style, derived from the template used to create it. MindManager comes with a variety of Map Styles you can use to instantly change the look of your map. You can apply a new Map Style to your map at any time, either when you begin a new map, or after you have already created a map.
If you have already created a map and you have applied formatting to individual topics, these topics will not be changed by applying a new Map Style unless you first remove the formatting you've applied. (see below)
On the Format tab, in the Styles group, click Map Style,
If you see the style you want
to use in the gallery, click it,
Otherwise click Assign from Template
Organizer, and you'll see a dialog
with style names and folders on the left side.
Click a style name to see a generic preview of it.
Select the style you want to use, and then click Apply. Choose the style that best meets your needs. You can modify it as desired and save it for re-use if you like.
In Multimap View, you can quickly apply a new style to one or more linked maps. Select the maps, then, in the Assign group, click Map Styles. Select the style in the organizer and click Apply.
Apply a Map Style from a file that doesn't appear in the organizer ▼
On the Format tab, in the Styles group, click the Map Style arrow, and then click Assign from File.
If you plan to use this style again, its advisable to add it to the Map Style Organizer:
On the Tools tab, in the Templates group, click Map Styles.
If you want to add the Map Style to a specific folder, select the folder in the left pane.
Click Add New Map Style, then click From Existing Style.
Choose the file containing the style you want to add to the organizer.
Mindjet Catalyst - If you want to apply a style from a file that is stored in a workspace, you must first save the style file (.mmas file) locally, then use the steps above to apply it from the local file.
A default Map Style, Default.mmas, is provided with MindManager. You can reset the map to this default style, modify this style like any other style, or use the style of the current map as the default from now on.
On the Format tab, in the Styles group, click the Map Style arrow, and then click Reset Current Map Style to Default.
You can also apply this style from the Template Organizer as described above.
On the Format tab, in the Styles group, click Map Style, and then click Make Current Map Style the Default.
A "backup" copy of this style, Default (original).mmas, is included with MindManager.
If you have already been working on the map for a while and decide to use a different style, you may wish to clear the formatting that you've applied before applying a new Map Style. The new style settings will not override any formatting that you have already applied.
Select the topics, boundaries or relationships whose formatting you want to clear (press CTRL+A to select all objects).
