I have created my Ribbon bar changes. I was attempting a dryrun of exporting and importing solutions before applying my changes to production. I have added Dropdown menus to the Ribbon Bar navigation. I assumed that these changes would be in the Model-Driven App but when I exported that solution my changes to the Ribbon Bar did not import.
Is there another part I need to add to a solution so that changes to a Ribbon Bar can exported and imported in to a different site?
