A pushpin is a user-placed control that provides a quick way to allow or prevent changes to an element’s position.
After you place a pushpin, you cannot move the element until you unpin it (by clicking the pushpin control). When the element is unpinned, a red X displays on the control. After moving the element, you can click the control again to pin the element to its new position.
For information on placing pushpin controls, see Preventing Elements from Moving.
