How to realize text slider?

Hi there,

that site is using a custom built slick-slider script for that carousel.

So any slider plugins should do the job.
What type of content are you wanting to add in your slideer ? Is it static text or a list of posts ?

Let's assume these are the latest posts from a certain category.

Hi Igor,

Here’s the WordPress repository for these kinds of plugins: https://wordpress.org/plugins/search/slick+slider+posts/
