The Fusion Settings page is available under Settings > Fusion within the WordPress Dashboard. Use the settings to setup the Fusion plugin with your theme.
Choose the post types on which Fusion will be available using the checkboxes.
You must check this option if not using the Fusion Base or if the active theme does not include Bootstrap. Fusion is built upon the popular Bootstrap framework, so if it is not enabled, Fusion will not function.
Use Fluid Grid
Check this option to fit the grid into the active theme's content container (will be required for most themes). This will make the “Container” and “Full Width” options for Rows redundant as the output will be virtually identical.
