Hi there and congrats on the really amazing plugin.
I am building a website for a martial arts school and the owner wants to create profiles of the athletes with custom information name, surname, date of birth, date of acquiring each belt, date of tournaments the athlete has participated, etc.
I created a custom post type using ACF and for the frontend I have built a template using the Divi theme builder that pulls data from the ACF custom fields.
My question is for the archive page of all the athletes. Is there a way to create a horizontal filter with the letters of the alphabet and the ability to filter the athletes by their name or surname initial letter?
An example of what I want to achieve can be found here: https://exthemes.net/teampress/
Awaiting your kind reply.
