YITH WooCommerce Product Add-Ons writes its block configurations into product postmeta and serialises the customer's choices into order item meta on every line that uses an add-on. The default admin shows them as plain strings under each order line, which makes any cross-store question a manual aggregation job.

SleekView reads wc_order_itemmeta alongside wc_order_items, parses the add-on line entries, and exposes them as columns: block label, option name, option price. Charts then turns those columns into a dashboard with revenue, attach-rate, and top-blocks views.

The dashboard stays on the WooCommerce side of the data. It charts what add-on revenue the store has already booked and which blocks customers actually picked, leaving raw plugin configuration to YITH's own screens.

Product add-ons quietly add a meaningful percentage to AOV on personalisation-heavy stores, yet WooCommerce's default reports lump them into the line totals without breaking them out. The data is already there: every selected add-on is recorded as order item meta on the line it belongs to. SleekView Charts surfaces that data as real columns and turns it into a Number, Bar, Pie, and Area dashboard.

Merchandising sees which blocks customers engage with, finance sees the revenue split, and marketing sees the daily trend. The plugin still owns the add-on UX and the cart logic; SleekView Charts visualises what every paid order has already recorded.
