Expanding code
When the code is collapsed, you can still copy, cut, or move it like you would any other selected element. You can then expand elements one at a time or all at once.
Click the Expand icon beside the line for the <nav> element.
The <nav> element expands, but the three <li> elements collapsed in the previous exercise are still collapsed.
Click the Expand icon beside the line for the <li> elements.
All collapsed elements are now expanded. Note that the Expand icon for the three <li> elements disappears altogether.
