Code Collapse Code collapsing provides the developer with the ability to highlight a segment of code and collapse it so that it's temporarily hidden from view. The obvious benefit to this is increased screen real-estate. To use the code collapse feature, follow these steps: 1. With the companydirectory.htm page open, switch to Code view if it's not already selected. 2. Highlight a section of code. Notice the line segments that appear in the line numbers column similar to Figure 3.56. Figure 3.56. Line segments appear in the line numbers column, indicating the segment of code that can be collapsed. [View full size image] 3. Choose one of the segment icons to collapse the code similar to Figure 3.57. Alternatively, you can choose the Collapse Selection button from the Code View toolbar. Notice the small plus (+) icon that appears next to the collapsed code.
