Rule Builder > Managing Decision Trees > Editing Operations on Tree Elements > Collapse / Expand

As the decision nodes and actions displayed constitute a tree, you can collapse and expand branches of this tree. Use the Collapse / Expand handles located on the right side of each node to collapse or expand the corresponding branch (images/minus_button.png and images/plus_button.gif for decision nodes and images/minus_action.png and images/plus_action.png for action nodes). Collapsed branches are not displayed. An example of an expanded and collapsed decision node branch (Category), and an expanded and collapsed action node branch (rule 4) are shown in Figure 13.37.
