Userform with Dropdown list and the ability to select more than one

I am so close to wrapping up my project, but am stumped on one field on my userform. I had originally created a combobox with a list of choices and now realize the user needs to be able to select more than one choice. I read where a listbox is the better choice, so I created the listbox instead and on the Properties menu selected "multi select." While this does work, I don't want the list to be visible with the choices highlighted in blue. In other words, I want the field to be one line and when it's clicked on it will then show the list to where the user can select more than one item. The results should be displayed separated by a comma, such as, "Physical, Dementia." The value of that field can go into the worksheet as-is with the commas. I don't need it separated out.

Thanks for any input!

Yes, I am using a UserForm. The listbox keeps the list expanded, and the choices highlighted. I just don't know if there's a code to accomplish what I'm wanting.
