# Product Customisation
During the ordering process, customers may be prompted to customise certain products like toppings or add-ons. These options are displayed in groups and can be either required or optional, depending on how the item is configured.
## Selection Prompts
Some menu items require the customer to select at least one topping or add-on before proceeding. These are indicated with a **quantity** next to the tick.
> For example:
>
> If a section indicates "**Select 1**", the customer must choose exactly one item. If it says "**Select up to 3**", the customer can choose up to three options or fewer. If it doesn't have any indicator, it is optional and may be skipped.
If requirements have not been met, the tick and the "**Next"** or "**Add to cart"** button will be greyed out.
## Dynamic Pricing
The item price is **automatically updated in real time** based on the selected add-ons. This allows the customer to see the total cost of the item with their chosen customisations before checkout.
## Summary Screen
Before the item is added to the basket, a **summary screen** appears showing the product name, all selected customisations, and the final price.
Customers can choose to confirm or go back to make adjustments.
