The final two options available by right-clicking a tag in the tag selector relate to expanding and collapsing code. They are particularly useful when working in split screen view.
Collapse Outside Full Tag is used to collapse all the code before and after a given element, allowing you to focus on the code representing the element itself. Thus, if you right click on a <form> tag and choose Collapse Outside Full Tag from the pop-up menu, the code preceding and following the <form> tag is collapsed.
To expand the collapsed code fragment, simply double-click on it..
