Hello Jenifer, thanks for the responding. Sorry I haven't gotten back to you sooner. You are referring to the "All Items" drop down list. The A-Z/Z-A drop down box sorts ONLY on the product titles. As my original question stated, I'm not asking how to sort the list based on product names. The Wishlist has no function to sort on vendors or vendor names and there is no other option I have yet figured out that will. I've tried the following scenarios:

0.) Starting condition: Select "My Wishlist" from the user activities drop down menu. Result: Returns a default list sorted on some (unknown to me) criteria. This is the "Default List".

1.) Select 'A-Z' from the "All Items" drop down list. Result: Activates an automatic return list of the product titles sorted alphabetically descending.

2.) Select 'Z-A' from the "All Items" drop down list. Result: Activates an automatic return list of the product titles sorted alphabetically ascending.

3.)Select 'Vendor' from the Title/Vendor search box. Hit the Search button. Result: Returns with the original Default List.

4.) Select 'Vendor' from the Title/Vendor drop down list. Perform steps from test (1.). Result: Automatically resets the Title/Vendor drop down list to 'Title'. Returns the original Default List.

5.) Select Vendor from the Title/Vendor search box. Type in "A" or "a"; capitalization doesn't seem to matter. Hit the Search button. Result: Returns a list of all vendors with "a" in their name. But the sort does NOT return an alphabetized list of vendors or products titles.

I've tried some other combinations but I'm not paid to do Usability testing anymore, so... It's been bugging me just because y'all have lots of multi-vendor sales, and I have to look up each vendor separately. Anyway, I look forward to seeing this fixed in the near future.

Happy New Year!
