Share an element across multiple pages
How can you share an element (such as a navigational menu, for example) across multiple screens/pages? I assume this is possible, but the only thing I've been able to figure out so far is how to copy an element and paste it onto multiple screens. However, when I need to make changes to that element, I don't want to have to update it in multiple places. Seems simple enough, but I can't figure out how to do it! Thanks in advance for any help.
