NSComboBox with multiple selection Cocoa

Question

Multiselect NSComboBox

Can we have a NSComboBox with multiple selection through checkboxes in OSx. Please find the attached image as an example.

Please help.

Please add some clarification. Do you want to change the menu of the combo box according to the selection of a radio buttons? — Daniel Farrell
@boyfarrell Thanks for replying, i have edited my question, does that helped to clarify my requirement? — Utkarsha
I recommend using an NSPopUpButton configured in pull-down mode and, as the user picks item, you adjust its title to reflect what's selected. — Ken Thomases
@KenThomases But how will you show multiple selection in NSPopUpButton? — Utkarsha
You can set the state of the menu items so they show a check mark. — Ken Thomases

According to the NSComboBox class reference - the answer is NO.

as you can see on the Manipulating the Selection:

@property(readonly) NSInteger indexOfSelectedItem
@property(readonly, strong) id objectValueOfSelectedItem

- deselectItemAtIndex: 
- selectItemAtIndex:
- selectItemWithObjectValue:

they refer to the selected item as single selection.

so I'd suggest looking for a custom solution, like keeping the selections on a different array and binding it together.
