The WinUI ComboBox control (multiselect combobox) is a selection component that allows users to type a value or choose an option from a list of predefined options. It has many features, such as data binding, multiple selection with checkboxes, editing, searching, filtering, UI customization, and custom templates.
Select an item or multiple items from the dropdown.
Select a single item from the dropdown list.
Select more than one item from the dropdown list. Checkboxes can be used to select items.
Display multiple selected items with token representation or simply divide them with a delimiter text.
Customized delimiters separate the selected items displayed in a multiple-select ComboBox. (e.g.: ‘-‘ as a delimiter character.)
Customizable token representation allows users to remove an item with its close button.
The ComboBox control supports editable and non-editable modes to choose items.
Edit the text in the text box. Suggestions will be shown in the dropdown list based on the input.
Items can be selected from the dropdown list, but the selected items cannot be edited.
The first item that fits the user input is highlighted in the dropdown list.
Filter the items in the dropdown based on the starting letter or on whether they contain a specific letter.
