Multi Select Dropdown List (Data Validation) for Excel Web version?

[lichldo]

Hello, I am trying to create a column where there is a drop down list in each cell and have the ability to select multiple options.

I know how to get the drop down list with data validation and I found this page that allows me to successfully select multiple (without repetition) with a VBA code.

However - this excel doc needs to live online (on sharepoint/onedrive) where the VBA becomes irrelevant.

Is there a way to set this up where it will work living online?

Thanks!
