Admin

Not saved on the server

See how a Magento-style admin is built: add custom products, and build condition-tree ("Conditions") cart pricing rules by category, SKU, product quantity, and total cart item count. Everything stays in your browser (localStorage) - the server only "sees" it for the duration of a request.

Custom products
Add your own product - it shows up in the Shop immediately, and any rule condition can reference its category/attributes.
Custom rules
Build your own "cart price rule" - it evaluates exactly like the fixed rules: in priority order, cascading, with a real condition tree.
