Once inside a tab, the template tree structure is visible. Depending on preference or necessity, we can control how the sub clauses are laid out. By default, when sub clauses are created they have a stacked appearance. Stacked is defined as being one on top of another. The screenshot below is a stack template tree structure. Notice how all of the sub clauses are one on top of another.
Tabbed and Flow present the same layout, however there is one difference. Tabbed layout is only for sub clauses that are not terminal. Flow layout is only for terminal nodes.
