From this section, you can re-order, hide or delete the content within your Navigation (and by extension, your entire Portfolio).
To reorder content, click and drag the next to each Navigation element.
To change the visibility of an element, click to toggle the element on or off. This will remove the page from your site completely. Alternatively, you can click the next to any line-item to remove or show it in your Navigation. From the gear, you can rename a Page along with lots of other options--each line-item in the popup has different capabilities.
