Configuration
The plugin has no config/container-deposits.php file - everything is configured through the control panel.
Field layout
The Container Deposit Type field must live somewhere on the purchasable's field layout. For most stores that's the Variant field layout:
- Commerce → System Settings → Product Types → [Your type]
- Open the Variants tab (or Product tab if your products aren't variant-based).
- Drag Container Deposit Type into the layout.
- Save.
The field stores the selected DepositType ID. The cart listener looks up the field on each line item's purchasable, so the field's handle can be anything you like.
Tax category
Container Deposits (No VAT) is created automatically on install and has no tax rates attached. If you delete it, deposits fall back to the store default category - re-running the install migration recreates it.
See VAT Treatment for details.
Currency
Deposit amounts are stored as floats and rendered using your active store currency. Set this under Commerce → System Settings → Stores.
