Hi @NaBian
this way we can solves the problem

public static readonly DependencyProperty IsDropDownOpenProperty = DependencyProperty.Register(
            "IsDropDownOpen", typeof(bool), typeof(CheckComboBox), new PropertyMetadata(ValueBoxes.FalseBox, OnValueChanged));

        private static void OnValueChanged(DependencyObject d, DependencyPropertyChangedEventArgs e)
        {
            var ctl = (CheckComboBox)d;
            ctl._popup.IsOpen = (bool)e.NewValue;
        }

But as you can see in the picture, the geometry is not updated (I think this problem can be solved easily)
What do you think about this? Is it the right way?

oh there is a new problem now We receive an error when the item is selected

 <hc:CheckComboBox>
                    <hc:CheckComboBoxItem Content="test"/>
                    <hc:CheckComboBoxItem Content="test"/>
                    <hc:CheckComboBoxItem Content="test"/>
                </hc:CheckComboBox>

There is no problem with the ItemSource
