Appearance
Settings
Lynx settings are in Stores › Configuration › Lynx. Like other Magento settings, most of them can be set for the whole installation, per website or per store view.
Theme Settings
Stores › Configuration › Lynx › Theme Settings chooses how the store looks: the Lynx design, and the Magento theme for what Lynx does not draw.
Active Design
The design shoppers see. See Designs.
Page Fallback
Some extensions bring storefront pages that Lynx does not design. Page Fallback shows those pages with a standard Magento theme instead, while the rest of the store stays on Lynx.
| Setting | What it does |
|---|---|
| Enable Fallback | Turns the feature on. When off, every page uses Lynx. Off by default. |
| Fallback Theme | The theme used for the listed pages, usually Magento Blank. |
| Fallback Routes | The pages to hand over, one per line. |
Pages are named the way Magento names them internally, such as shipping_tracking_popup. A line ending in * covers every page that starts with it, so multishipping_* covers every page of checkout with multiple addresses. If you are not sure of a page's name, ask the developer of the extension that adds it.
By default the list holds the pages Lynx has none of: checkout with multiple addresses, the shipment tracking popup, PayPal billing agreements, the PayPal Payflow pages and the payment pages of Magento's payment services. The Lynx checkout and the PayPal review page stay on Lynx.
Email
Email Theme is the Magento theme emails of the store are drawn with, such as order confirmations. It defaults to Magento Blank; pick the theme the store used before Lynx, such as Magento Luma, to keep the look of its emails. The theme must stay installed.
Customer Address Fields
Stores › Attributes › Customer Address Fields sets the fields of every Lynx address form: the checkout (shipping address, and billing address when it differs), the address book in the customer account, and the address part of the registration form. It lists every visible customer address attribute, including the ones you create.
| Column | What it does |
|---|---|
| Order | Drag a row to move the field. The forms show the fields from top to bottom in this order. |
| Width | Half puts two fields side by side, Full gives the field the whole row |
| Required | Whether the field must be filled in. First name, last name, street, city and country are always required, since Magento requires them. |
| Minimum and Maximum Text Length | Length limits; empty for none |
| Input Validation | Only letters, only numbers, letters and numbers, an email address or a URL |
| Forms | Where the field shows: Customer Account Address for the address book, Customer Address Registration for registration and the checkout |
These are Magento's own attribute settings, so the store checks the same rules when an address is saved, whether from the storefront, the admin or the API. Labels follow your translations. State and ZIP code are required or optional depending on the country the shopper picks, following Stores › Configuration › General.
To ask for something extra, such as a delivery note or a tax number, create a customer address attribute in Stores › Attributes › Customer Address, make it visible, and tick the forms it belongs to here.
The registration form asks for an address only when Show Address Fields is on in its Create Account Form component.
Server-side rendering
Settings for rendering pages on the server are in Stores › Configuration › Lynx › SSR. The renderer runs as a Node.js process or as a Cloudflare Worker. See Server-side Rendering for every setting.
MCP Server
The MCP Server lets AI assistants that support the Model Context Protocol connect to your store and work with Lynx, for example to build pages in the editor. See Build with AI for what they can do.
Its settings are in Stores › Configuration › Lynx › MCP Server, and connected assistants are approved and managed under Lynx › MCP. An assistant can only do what the role of the admin user who approved it allows. Your developer runs the MCP server, see MCP Server.
Permissions
Each section of Stores › Configuration › Lynx has its own permission in System › Permissions › User Roles, under Stores › Settings › Configuration. A role without it does not see that section.
| Section | Permission |
|---|---|
| Theme Settings | Lynx Theme Settings Section |
| SSR | Lynx Inertia Section |
| MCP Server | Lynx MCP Section |
Permissions for the editor itself are described in The Editor.
