Crelly Slider


Crelly Slider is a Free / Open Source responsive WordPress slider that supports layers. You can add Texts, Images, YouTube/Vimeo videos using a powerful Drag & Drop Builder and animate each of them. It is perfect to display your creative content in posts and pages.

Official WebSite (with live demo)

User Friendly Admin Panel

Crelly Slider does not require any Coding Knowledge. With the simple admin panel you will be able to create the sliders in the easiest way. Upload images with the default WordPress interface or choose colors using the picker.

High Cross Browser Compatibility

Most of the animations and the transitions are written in jQuery (using the “animate” function). In this way we can assure the compatibility with modern (even Android and iOs) and older browsers.

Drag and Drop Builder

How can you position all the elements in to the slider area? You just simply drag them in to the desired position. Like in Powerpoint, you just have to move the object around the Slide.

Transitions & Animations

Foreach element and slide you can choose an in animation and an out animation using a simple selection menu. You can set the transition speeds and how long the element will take to get in and out.

Completely Responsive

Responsive means that the Slider will be displayed correctly in every resolution that the user will use. If the display is small (like in a smartphone), the slides and the elements will be scaled to be adapted.

Full & Fixed Width Modes

Using Crelly Slider you can select between a fixed or a full-width layout (both of them can be responsive). You are the designer, you own the WebSite, just choose the best for it.

I installed it in WP 6.0.3 and it doesn’t work, it can’t be seen, although I see that it is in the code.

I can say better than many premium plugins. We couldn’t fix a conflict issue with the theme I am using (Astra Pro) but I still keep using it and can recommend it.

I used it for one of my customer website which result in giving premium quality lightweight layer slider. I request to keep it free or opensource. I have not faced any issue. Simple interface.
