You can change the level of a feature, relative to the other features in your application. By ensuring that your feature hierarchy is well structured, you can make it easier for users in other applications to reuse or extend your features.
In the header of Designer Studio, click the name of your current application, and then click Overview to open the Application Overview landing page.
In the Features section, click the Switch to tree view icon.
Expand the list of features and subfeatures to review the different levels in your feature hierarchy.
Drag a feature to a new position in the list to change its level and the level of its subfeatures.
You cannot change the level of a feature if it has dependencies from applications that build on your application, or later versions of your application.
