Portfolio – Alphabetical filtering through pagination

Hello,

In an attempt to explore several solutions following my previous post, here I’d like to know how it would be possible to filter the elements listed from the Portfolio, in a way the User could be able to choose in alphabetical sections such as : A-M / N-Z

Showing then the elements starting with the good letter… I already have made the little trick to display them in alphabetical order, coming from an old post in the forum.

Any tips would be great !

Thanks,
