mousemove+eventstructur
Hello zäpfle,
what do you mean by "open and close"?
Should the control appear and vanish on mouse over/leave? Or should all data items be visible at once (like a context menu appearing on right mouse click)?

Sounds like what you really want to do is simulate a mouse click to drop open the list box.
There is no property to do this, but there is hope. Check out this thread for some VI's that simulate mouse clicks.
For you're event structure, you probably want to use the "Mouse Enter" event to trigger the click instead of the "Mouse Move" event. That way it only gets triggered once when the mouse first enters the control bounds.
Let us know if this works out for you.

Using the Abort button to stop your VI is like using a tree to stop your car. It works, but there may be consequences.
Not sure how useful that thread will be, Ed. The URL returns a 404 and the .vis in the .llb cannot be opened in LV8.0 (no block diagrams or some such) 
Hello Zäpfle,
yes we could communicate in german, but most of the guys here only understand english. This way you get far more answers...
I would do the following:
Read the data items from the ring, format a string of them and feed a string indicator with this string. On "Mouse Enter" you make the string visible, on "Mouse Leave" you hide the string. It's the easy way with enough possibilities to do the formatting of the string.
It will not look like a pull down menu, but you can search for this in the forum too. There are some examples that show how to do "pull down menus" even in LV7.0.

I guess I should have checked that first.If you just do a search on the forums for "Simulate Mouse Click", you'll get quite a few threads that cover this subject. Maybe one of them will have something useful.
