I figured it out:
我想到了：
layoutMenus.Show(Cursor.Position.X, Cursor.Position.Y);

Make sure that when you're positioning the context menu that you pass it the correct screen coordinates. You'll need to use something like Control.PointToScreen, using the x, y, coordinates based on the position of the control in its parent.
确保在定位上下文菜单时向它传递正确的屏幕坐标。您需要使用 Control.PointToScreen 之类的东西，使用基于控件在其父控件中的位置的 x、y 坐标。

I know this is an old question but I think it may help other people. Following code will display the context menu just below the button being clicked and the button will look like a dropdown button.
我知道这是一个老问题，但我认为它可以帮助其他人。以下代码将在被单击的按钮下方显示上下文菜单，该按钮看起来像一个下拉按钮。
private void Button1_Click(object sender, EventArgs e)
{
Button btnSender = (Button)sender;
Point ptLowerLeft = new Point(0, btnSender.Height);
ptLowerLeft = btnSender.PointToScreen(ptLowerLeft);
ctMenuStrip.Show(ptLowerLeft);
}

As far as I know the code you require was here:
据我所知，您需要的代码在这里：
// On the right of the button
// 在按钮的右边
ContextMenuName.Show(ButtonName.Left + ButtonName.Width + this.Left, ButtonName.Top + this.Top);
At the bottom of the button
在按钮底部
ContextMenuName.Show(ButtonName.Left + this.Left, ButtonName.Top + ButtonName.Height + this.Top);
At the bottom right of the button
在按钮的右下角
ContextMenuName.Show(ButtonName.Left + ButtonName.Width + this.Left, ButtonName.Top + ButtonName.Height + this.Top);

ContexMenuName under button, aligned to the right side of button (expands to below button and to the left):
ContexMenuName.Show(ButtonName, new Point(ButtonName.Width - ContexMenuName.Width, ButtonName.Height));
Hope this will help sb :)
按钮下的 ContexMenuName，与按钮右侧对齐（扩展到按钮下方和左侧）：
ContexMenuName.Show(ButtonName, new Point(ButtonName.Width - ContexMenuName.Width, ButtonName.Height));
希望这对某人有所帮助 :)
