The WooCommerce Update Variations in Cart plugin allows users to change and update product variations based on attributes (color, size, weight, type, etc.) directly from the cart page without disrupting the user flow. No page reload; update the cart with AJAX.

• • No configuration, no coding required: Just install and activate the plugin, and that’s it. You don’t require any technical bits. Simple and straightforward.
  • Instant and automatic: All existing and newly created variable products will automatically be enabled with the feature to change variations in the cart.
  • Change multiple product variants in one go: Your user can change variations for multiple products on the cart page. Select variants and click on Update. The changes will be automatically reflected along with the change in price, if any.
  • Edit the ‘Change variation’ link: You get the option to change the text for the ‘Change variation’ link. ‘Update Variation,’ ‘Switch Variation’… keep whatever you feel like.
  • Support for custom product attributes: Have you created custom product attributes for unique products? Your user can change that too from the cart page for that product.
  • Works with WooCommerce subscriptions: If a user has added any subscription product variant and wants to update it, like updating from a single-year subscription license to a five-year license, the user can do it from the cart itself.
