Can I give an item multiple values for one attribute?
To apply multiple values to an attribute for a single item, you can separate them with a semicolon. For example, an item that is both Red and Blue (for a "Color" filter) the value should be "Red;Blue" so that the WebAlliance system recognizes that there are two separate values.
Be aware that certain WebAlliance functions might behave in unexpected ways if you do this. For example, an attribute that allows for multiple answers is good for browsing filters, but is not good for featured filters in Row View. Row View featured filters show a single attribute value per item, so if an item has more than one value then the user wouldn't see the whole answer.
