Multiple submenu levels for Sparkling theme and - right sidebar layout

Sparkling

  1. This theme doesn’t support multiple submenu levels. However, there is a workaround that you can find here.

  2. You can change layout settings via Appearance >> Theme Options >> Main >> Website Layout Options. Choose “Right Sidebar” and save changes. Since “Right Sidebar” is default option for this theme it means that you have already changed this setting before.

Let me know if this helps.
