We apologize for the instability of composr.app and appreciate your patience. We are working on the statistics addon and trying to find an optimal way to store and render data. Unfortunately, we have yet to find a solution that can handle the traffic (and therefore, tens of millions of statistical records) of composr.app. We're working hard on one.
Ignore the bit about multi-level tree menu's, if you set a link on the parent then it fails to expand/contact the children but it you leave it blank it works fine.
But I'll add to the docs:
"For a branch with children that branch can be set to be initially expanded or contracted. Note that the expand/contract setting may not do anything; some menu types don't use it, and if you enter a Link then it probably would be displayed auto-expanded anyway (due to clickability on the parent being used to open that link, not expand)."
I ran an actual test, it displays as per the above documentation. i.e. expand/contract is ignored, and it's auto-expanded, if a Link is given on the parent.
Any menu type may do what it wants. It is conceivable of a menu type with separate expand/contract icons, but none has been written so far because users would probably find such a menu overly technical for a public-facing website.
