Creating A Custom Layout Section
If you already have a Layout you want to add a Custom Footer Layout Section to, or you want to add it to the Global Layout, then you can go ahead and create a Footer Layout Section.
You can do this on the Layout Section Builder page, by simply choosing the type of Layout Section, and then adding a name (in this case, Footer, and perhaps a name of Global Footer might be most appropriate) and then clicking on Create New Layout Section, as can be seen below.
Alternatively, you can create a Layout Section directly from the Layout you wish to add it to, as can be seen below. For a Layout Section to appear on your site, it has to be added to a Layout. And as mentioned, there is initially only a Global Layout. So, if you wanted to create a Global Custom Footer, you would just add it to this Layout. But if you wanted a conditional Custom Footer, you would need to create a new Layout, assign a Custom Footer Layout Section to it, and then add conditions to it to get the Layout to display according to those conditions.
There’s no wrong way to do this, but it’s important to think of the circumstances. If the layout is already active (i.e. it has conditions or is the Global Layout) then any Layout Section added would also be immediately active, and at this point would still be empty. So in the example of adding a Custom Footer to a Global Layout, it would make more sense to add it via the Layout Section Builder page first, and build it before adding it to the Global Layout.
Alternatively, if we were adding a Footer Layout Section to A Conditional Layout, then we could add it in this way, and then build it. Conditional Layouts are not in use until there are conditions added. If we mouse over the Footer Layout Section on the Layout, as shown below, we can then click on the edit icon to design and build our Layout Section.
