Keep a ToolStripDropDownButton dropped down for multiple selections

Question

I have a ToolStripDropDownButton that has multiple children and I'm using them as checkboxes (CheckOnClick=True) so you can check multiple child items.

My question is: how do I keep the parent item "dropped down" so it doesn't close up every time you click a child item?

Answer 1

So simple I overlooked it - in the click event handler, just call ShowDropDown() on the parent.
