Inserting Promotional Blocks After Every Fourth Ditto Item

Content listings often need one extra editorial rule: after every few news items, show a banner, promo block, or subscription prompt. In Ditto-based sites, this is usually solved through iteration-aware template logic rather than through separate manual inserts.

The important part is to inject the extra block at predictable intervals without disturbing pagination or the markup structure.

A practical pattern

• use the item iteration counter,
• test whether the current row index is divisible by the chosen interval,
• print the promo block only after the target item,
• keep the promo markup outside the normal item template if it differs significantly.

This produces a stable layout and keeps the listing maintainable. Editors get a repeatable rule, and developers do not have to hardcode banners into the content feed itself.

Any “insert after every N items” requirement becomes much easier once the listing logic owns the interval explicitly.
