I want my customers can reorder multiple products, not an entire previous order, in Magento 2. They can select which products they ordered previously to repurchase them.
Thanks in advance.
Well, we recommend using Magento 2 Reorder Product extension
This module will help your customers to reorder previously purchased products quickly in their Accounts.
Hope it helps.
Reorder previous products extension adds a grid on the frontend that contains key details related to previous purchases made by the customer. They can reorder products directly from this grid that saves time and allows customers to reorder their favorite products.
The following link Magento 2 Previously Ordered Products would be useful.
