Why do this? If it is getting to hard to specify the criteria for a collection (e.g. if you need “ands and Ors and nots”) then it is easier to turn the collection into a customer collection
Unfortunately we need to delete the existing collection to do this, so before you do it
Rename your old collection as the old one by changing both the title and handle (at the bottom of the page)
Create a new collection, with the same name – e.g. Women’s Vests
Copy across the Collection Description (if there is one), and also (if there is one)copy across the Collection Featured Image (you can open it on the old collection, right click on the image, and copy the url, or save it to desktop and re-import it if that is easier)
Now add the products to the collection:
Remember to SAVE!
The next step is to add the NEW collection to your navigation.
First figure out where it shows in the drop downs: - in this case “womens” then “Vests”
Go to Navigation (admin/link-lists)
And find the drop down list(s) in which the collection link is shown
Then use the drop down to choose the new collection, rather than the old one (marked with an X)
Remember to Save
Go to your website and test – remember you may need to refresh the screen.
Once you are happy, delete the old collection (the one with an x). This is important to avoid confusing google.
