Hi All,

I have a dynamic dataset of products and I display them using a repeater. I use $w( ‘#repeater1’ ).onItemReady to compute a ‘Recommendation’ rating for each product. This rating is computed on the fly and is not part of the product dataset. I display this rating using one of the elements in the repeater item.

How do I sort/filter the product list in the repeater based on this external value?

Here is my code snippet:  
$w.onReady( **function** () {  
$w( ‘#repeater1’ ).onItemReady(($item, itemData, index) =\> {  
**let** rating= calculateRating(itemData);  
$item( ‘#ratingsDisplay1’ ).rating = rating;  
});  
});
