OptToFly lets you sell products with extra options and add-ons without creating more variants. Build buttons, dropdowns, swatches, radio buttons, checkboxes, text fields, and date pickers, with images and descriptions for each choice. Link each add-on to another product or variant, or set a fixed amount on Shopify Plus. Reuse option groups across products with add-on sets, style and translate the widget to match your theme, and track option orders from your dashboard.

• Responsive swatches and option fields let customers customize on product pages.
• Add custom modifications to any item to completely bypass variant limits.
• Automatically sends customer selections to your Shopify checkout and orders.
• Create an add-on set once and apply it across many products in a few clicks.
• Style the widget to match your theme and translate every text label.
