The Modular with Sidebar template works best for internal pages that may be more text-driven, but that still need the flexible functionality offered by modular content blocks.
Each Modular with Sidebar page includes the standard modular content block features for its main content column, and a number of flexible options for the sidebar as well, including automatically generated section navigation, a standard page sidebar, and custom, page-specific sidebar content, all of which are optional and can be arranged in any order.
