The following Multi Select elements are fields that eBay gives you to select multiple options from the drop down. Ebay has 2 pages, that do the same thing but the code is different. For the old and new element, what selector(ie ".class #id etc...) would work for both of these elements so that it allows me to determine that this is indeed a mutli-select drop down field. I have included an example of a single select, that we should not select. Ignore any item specific identifiers like "MPN" as these would change on every field.
