Searchspring provides several strategies to sort the values presented to your customers in each facet in your Field Faceting options. This includes sorting Alphabetical, by the number of results each option represents (Count), Reverse Alphabetical, Clothing Sizes, and Grade Level. However, sometimes your facet options may require a specific sorting that is not covered by one of these strategies. This is where Custom (Advanced) will help.
After selecting this option from the "Sort" drop down, click "Advanced" on the right.
Enter values, one per line, in the order that you would like them to appear. Values in your feed that are not listed in this box will display after values that are specified.
A customer lists out the following "Color" values:
Blue Yellow Red Orange
However, they also have the "Black" as a "Color" attribute in their feed. On their website, the facet option order would look like this:
Blue Yellow Red Orange Black
