I got the solution, we can do this is folowing way:
我得到了解决方案，我们可以通过以下方式做到这一点：
ContextMenu contextmenu = new ContextMenu();
ComboBox CmbColorMenu = new ComboBox();
CmbColorMenu.ItemsSource = FontColors;// FontColors is list<objects>
CmbColorMenu.DisplayMemberPath = "Text";
contextmenu.Items.Add(CmbColorMenu);

The following code is just a proof of concept on how you could build your ContextMenu. It will give you a ComboBoxas the content of a MenuItem.
以下代码只是关于如何构建ContextMenu. 它会给你 aComboBox作为a的内容MenuItem。
<Label Content="label with context menu">
<Label.ContextMenu>
<ContextMenu>
<MenuItem Header="menu 1">
<ComboBox>
<ComboBoxItem Content="combo 1" IsSelected="True" />
<ComboBoxItem Content="combo 2" />
<ComboBoxItem Content="combo 3" />
</ComboBox>
</MenuItem>
</ContextMenu>
</Label.ContextMenu>
</Label>

Another alternative...this allows the ComboBox to appear directly when you do the Right-Click. Copy and paste this into KAXAML to see it working.
另一种选择...这允许组合框在您右键单击时直接出现。将其复制并粘贴到 KAXAML 中以查看其工作情况。
