To display only the slide title, you can go to your Dashboard -> Pages and there you can edit the page to be displayed on the slider by removing its content.
Thanks
But the content itself is usefull but only on dedicated page, not necessarily on main page (for instance by clicking on read more) 😉
In the meantime i found solution. It need to add these lines in custom.css
.caption-sub {
display: none;
}
.slider-readmore {
margin: 50px auto;
}
Maybe it will be usefull to someone
Best regards !
