Hi Luke
I'm Anna and I'd be happy to help you with your question. In this Forum, we are Microsoft consumers just like yourself.
It is not possible to insert a multiple-selection list box in Word using the built-in features of the program. However, you can achieve this by using a Word add-in or macro. One popular add-in that allows you to create multiple-selection list boxes in Word is called "Combo Box". Another option is to use a macro to create a custom multiple-selection list box.
I hope this helps ;-), let me know if this is contrary to what you need, I would still be helpful to answer more of your questions.
Best Regards,
Anna
