        },
        inject: true,
        on: {
            change: ($inject, value) => {
                // Auto-calculate total price from quantity and unit price
                const price = $inject.api.getValue('price') || 0;
                $inject.api.setValue('total', (price * value).toFixed(2));
            },
        },
    },
    {
        type: "InputNumber",
        field: "price",

        inject: true,
        on: {
            change: ($inject, value) => {
                // Auto-calculate total price from quantity and unit price
                const quantity = $inject.api.getValue('quantity') || 0;
                $inject.api.setValue('total', (value * quantity).toFixed(2));
            },
        },
    },
