📍 Bolt Help / Developer Resources / References / Dynamic Customization Options Dynamic Customization Options Learn about the rules and conditions available for dynamic features such as custom notices and custom checkboxes. Page Contents Click to expand. This guide will help developers build rules for dynamic features. Dynamic features enable a merchant to create a library of rules that conditionally populate information while the shopper checks out. Supported Features Dynamic Custom Fields Custom Notifications Conditions Logic Conditions drive the logic of rules and are checked when a Shopper interacts with Bolt Checkout. You can add multiple conditions together using && to create complex rules. Reference the Rules Engine for a list of all possible operators.

There are two main commands you can use with Bolt: Display Notices: Message => "Delivery to this region is currently unavailable." Display Checkbox: checkbox => confirm_21 Convert $€¥ to Integer: toMonetary(<NUMBER>); toMonetary(10.12) == 1012 Round to Ceiling: ceil(<INT>); You are $%ceil(toMonetary(150) - Cart.TotalAmount)% away from free shipping Integration Examples Example One Expression: any(Items, {.SKU in ["MATTRESS01-C","MATTRESS01", "MBASE05"]}) Command: Message => "Mattresses and Comfort Bases only ship to US addresses. PO boxes and APO/FPO addresses cannot be accommodated at this time."
