I have a ComboBox on my form, the logic of which differs from the usual one. It contains check boxes. When checking checkboxes, a list of checked values ​​is displayed in ComboBox.Text. This happens in the event handler. To avoid the user selecting an object (namely, selecting an element, not selecting a checkbox), in the ComboBox.SelectionChanged handler I set the selected object to null. But at the same time, the ComboBox stops displaying the list of values ​​and shows an empty line.

in WPF I want to use a combobox powered by Richtextbox (or something allowing me to do the same). Richtextbox contains text and images on the same line. I would like when we click on the comboxbox that we can see each item with the text + images, and when we select an element of the Combobox, it appears as a selected element and appears correctly with the text and the images. Is it possible (I guess yes) in this case, how to do it using the MVVM pattern?

Here’s my ComboBox within a ListBox:
