Related Post Slider Block

This block picks the posts that have the same category/categories of the current post and display them in a carousel slider.

To insert and use the block, inside the post editor, underneath the main post content (or any position you wish), type ‘/related’, you should see the block called ‘Related Post Slider Block’. Choose and insert it to the post editor.

– Toggle on/off featured image for each slide.

1. Assign categories for the post
2. Click Publish/Update/Save draft when you finish editing the post
3. Delete the slider block you’ve inserted before

If the slider in the post editor appears and is functional but not on the frontend, please make sure jQuery is enabled for your WordPress site.
