How to create combobox when selected item it adds this anywhere?

How to this for combobox?I have long stackpanel which first it has only c开发者_Python百科ombobox.And when i select anything from combobox it will be added as button or other thing like on the picture.And it can be closed

The combo box that ships with WPF does not support selecting multiple items... This article describes a WPF combo box that supports both. It also describes a list box, which the combo box inherits from, that supports binding to the SelectedItems

Alternatively: WPF: ComboBox with CheckBoxes as items (it will even update on the fly!)

Recently I’ve come across something weird… I needed a ComboBox that will allow the user to select multiple items. The the solution coming to mind is using CheckBoxes. I have found several examples, but neither one displayed the selected items with pretty commas like this;

i m not sure what you are asking for but you can use this.
