Sticky Post badge in Oxygen builder Repeater

If you want to display badge over your posts displayed within Oxygen Builder Repeater element in WordPress, than I hope I have a solution for you.

Set the post to be sticky (featured) in the Gutenberg editor:

Add Sticky (Featured) post badge to repeater

Add a div to your post container inside the repeater. Then put the text element inside with your badge text. Add a classes and style it. Here is how my green badge should look like:

It has been done with this css:

.post-card {
     position: relative;
}
.badge {
     position:absolute;
     top:0px;
     left:0px;
}
.badge .featured {
     background:green;
     width:40px;
     height:40px;
     display: flex;
     flex-direction: column;
     align-items: center;
     justify-content: center;
}

Add a conditional with PHP Function Return value:

Set the conditional to display only when it's not blank:

You are done. Your badge will automatically display on featured posts in repeater.
