Style System.Windows.Controls.ComboBox to not display selectedItem

Question

I am creating a comboBox in c# to handle a list. Please look into the picture.

What I want is to make the selectedItem not to display after I select any item.

The desired outcome will be like this: expected output. Furthermore, if can make it to display like a button, that will be better.

Any idea how to do so?

Simple example: V is the toggleButton

Original:

selectedItem | V
 item1
 item2
 item3

What I want:

V
 item1
 item2
 item3

@ASh because the comboBox has a toggle button itself, I wonder if can remove the selectedItemContainer, then remain only the toggle button. — Jack Lee, Feb 10 '21 at 12:16

You will need to edit a ControlTemplate for your ComboBox and reference it either directly or throught style for your ComboBox:

You can remove the ContentPreseter named ContentSite, and all refernces to it in triggers and storyboards.

In the ComboBoxItem you will have to remove triggers/storyboard that work when its IsSelected is true.
