Load configurable product with preselected options of any one of simple product

Question

How to load configurable product with preselected options of any one of simple product?

For example

I have a configurable product http://host/product/1.

It have 2 associated simple products http://host/product/2 and http://host/product/3.

Whenever configurable product page load, I need to display the preselected options of http://host/product/2.

Can anyone share hints to achieve this?

Hi I'm in same situation. Below is my implementation (not completed yet but I believe to be "clean" solution):

• override Magento_ConfigurableProduct::product/view/type/options/configurable.phtml in custom module, adding code to check how many child products the configurable product has (if only one, then don't render the options).

This also requires adding a Plugin class for the swatches module due to stupid magento2 hard coded template paths, refer to https://github.com/magento/magento2/issues/4400

• create custom js component that takes the child product id available in the phtml template. This component will set the value of the "selected_configurable_option" hidden input field to that product id.

This should be enough to allow customer to set quantity and add to the cart.

I usually do only backend side so am looking up minimal way to create this js component (or do it inline if possible).

FYI this is not a fully tested or complete solution as I haven't check what these overrides do when customer is editing their cart or browsing category products.

I'm still working on it as of this post.

This free module does the job! :) https://github.com/magepow/magento-2-configurable-preselect
it also has an option to view preselected options in listing page
