ActiveX ComboBox DropDown

I have an activeX combobox on my spreadsheet. When I show it, it is collapsed but I can make it show already dropped down by using the DropDown method (not shown in any documentation that I can find). However, if I then want to then hide the combobox by setting visible property set to false, it still shows on my worksheet. How do I hide the box without selecting anything. Note that if I select something from the list, it seems to collapse but still won't become hidden. How do I control the visiblity of the combobox after I use the DropDown method?

Thanks..good idea but would sure like to have more elegant solution. Tried setting combox1.DroppedDown property to false but apparently the ActiveX ComboBox does not recognize the DroppedDown property.

Apparently DropDown is a Method and not a Property. When I executed in VBA the code ComboBox1.DropDown the box shows as drops down. When I set the visible property to False, it continues to show on the screen. The Combobox has a property of DroppedDown but this gives an error in VBA (look up the properties of a combobox and you will see). I cannot find any listing of either properties or methods that show the DropDown Method (I found this by trial and error).

I am using a CB who's list I create using additem each time the User needs to select from the box. I am trying to find a more direct solution than a work around like using zero width. I would have thought that there would have been a command to collapse a combo box since there is the DropDown method. After all, what goes down usually comes back up!

NO, I'm not using validation...I populate the list box each time the user clicks a "Select" button. I have tried the DroppedDown property setting but this gives me an error. I don't think the DroppedDown propery can be set for a combobox in VBA. As I said, I can show the comboox in the dropped down state by using the ComboBox.DropDown method. Just can then get it hide when I set the visible property and the disabled properties to false...it just keeps showing in the dropped down state on the screen.
