Global header and footer

I have to ask here, because there is no documentation for these components.

Are they supposed to appear on every page? Is there something that has to be set to get them to appear on every page? If not, how do I copy them to other pages? Although the components are copyable (sorry), they won’t paste on another page.

Once you convert a component to Global, it will show up in the components panel. You then just drag the to each page that you want them on, just like any other component.

further to ercross statement just remember when altering a global it will alter all of them unless you unlink on certain pages

And just to add to this conversation… you should check out the Globals documentation in the manual, and especially the video to understand how they work.
