I have spent ages trying to find this, but I want a navigation layer to stay where it is on the page when everything else scrolls, and keep reading about the Static Layer action - but I can’t find it anywhere in my installation. Is this an old action which has been replaced by something else?
That is all excellent stuff so thanks to those who have helped.
I discovered this morning that I need to make a decision on how much I want this feature on the site I am working on.
The reason being, everything is currently set up as layers within a relative layout because it was originally going to have tiled backgrounds on a centred site, and since asking this question, I have discovered that the only thing that can be a layer is the item I want to scroll!
I have tried playing around with taking everything off layers and out of a relative layout, but it all goes a bit wrong so I need to decide if it is worth spending the time starting again or not.
