I have a Lightning Record page that has a section with a case page layout. When I retrieve the metadata for the Flexipage, the markup for the section with the page layout looks like this:
<flexiPageRegions> <componentInstances> <componentName>force:detailPanel</componentName> </componentInstances> <name>main</name> <type>Region</type> </flexiPageRegions>
Where is the layout used in this section defined? I did a find across files for the layout name and can't find anything that looks promising. Does it perhaps inherit from an org setting somewhere - does setting the layout used have to be a manual step (this is a valid answer, but looking for confirmation)?
