I’m using a category (let’s name it “featured”), so i can place some important posts at my homepage. What i want is to limit the posts at that category (let’s say only one post), so when an editor tries to add a new post to the “featured” category, he should first remove the older post.

Not native speaker, hope it makes sense.

Any help would be much appreciated

You can try this plugin : https://www.ads-software.com/plugins/blog-designer-for-post-and-widget/

To display the posts category wise you can use the shortcode :

[wpspw_post category="category_id"]

Any updates?

Have you written the custom code to display the posts?

I guess a php function that allows me to set limit of posts to a category, will do the job, but i can’t find something close to what i want.
