I am trying to build a custom container. I have created a separate object for my header and set User.msvStructureType = "Heading"
I'd expect that when selecting the container, any text I type will be in the header but that's not the case.
The text is showing up centered in the container.
How can I have my container behave like the built in containers, when you select the container and type any text it is automatically placed into the header?
