When you set the "Show collapsed on startup" on an expander container for a transition or state form, the first time you open the form this is correct. If you then expand the container then whenever the form is loaded again it is not set back to collapsed as it should be per the property.
An expander container will retain a collapsed state from when the form was last used and does not allow you to expand it unless you click the expander so the arrows are pointing upwards (indicating that it should be opened), then save/exit the form and reload it which will have it fully expanded upon form load. Problem appears to exhibit only within transition forms and in any browser type/version. Keywords : collapse section hidden
In Composer, form actions that will watch, read, or expanded/collapsed the section only impacts Expanders. However, Composer will allow you to select Group Boxes and Panels too. The list of objects should be restricted to only Expanders .
