A minor new release of CB Code Field is now available implementing a great new feature for searchable selects! Check out the details below.
You can now toggle on Filterable Single and Multi Code Select options. This allows a user to type into the search input and for it to communicate back to the field that it was filtered. You can then apply, within your custom PHP, filtering logic to output a different set of options based off that search.
This is highly useful if you're pulling your options from an external service as you can now make those external options contingent on the user typing in a more specific context.
In addition to this there have been multiple internal cleanup efforts within the code itself to improve performance and reliability. For more details about this addon please check out the page below.
