When you click on an embedded component section from group within UI Designer, you cannot see all the different components available for that selection.
- SAP Cloud Applications Studio
- SAP Cloud for Customer
- SAP Business ByDesign
This is the expected behavior. On clicking an embedded component only the EmbeddComponent section gets selected.
In order to view all the components you should right click on the EC -> Go to Select -> Click on EmbeddedComponentPane.
