Basing modifier options on existing menu items

To base a modifier option on an existing menu item, you start by going to a modifier group's details page and, in the Modifiers section, setting the Source configuration option to Manually create modifiers. When you choose this option, a Modifiers grid appears on the page. Click the Add button below the grid, choose New Modifier from Existing Item from the drop-down list, and then choose the menu item you want to base the modifier option on from the Select Menu Items dialog box. The Toast platform creates the new modifier option and displays the modifier option's details page. On this page, you see the Pricing section and its Override item price configuration option.

The Override item price configuration option specifies whether the price of the underlying item reference is used for the modifier option or if that price is overridden by a price specified for that modifier option. The Override item price configuration option applies only when the parent modifier group is configured to set prices on individual modifiers (the Select where pricing is set configuration option is set to Additional charge - price set on individual modifiers). If the parent modifier group either does not charge for its modifier options or sets the price of its modifier options at the group level, then the Override item price configuration option is ignored.

When you set the Override item price configuration option to Yes, a Price override configuration option appears where you can specify the override price of the modifier option. Override prices are constant prices that do not change based on other conditions, such as the time when an order is placed. The override price that you set is the price you see for the modifier option in the Modifiers grid on the parent modifier group's details page. You can edit the override price directly in the Modifiers grid, or on the modifier option details page, and it only affects the modifier option price, not the underlying item reference's price.

When you set the Override item price configuration option to No, the Modifiers grid displays the price of each modifier option's item reference. Whatever pricing strategy the item reference uses is reflected in the Modifiers grid. The grid includes an icon to identify the pricing strategy used by the item reference. For example, in the illustration below, the Steak modifier option's item reference uses the time-based pricing strategy, as indicated by the clock icon.

If the item reference uses the Base pricing strategy, you can edit that base price directly in the Modifiers grid. This changes the price for both the modifier option and the underlying item reference. If the item reference uses any other pricing strategy, you must edit the price on the details page for the item reference itself (see Understanding a modifier option's item reference for information on viewing the details page for an item reference).
