Make a store variant inactive if you no longer require the variant to be available for purchase.
First head to your store inventory, and click on the product you would like to make inactive.
Click options besides the variant you would like to update, and then change the status to inactive.
The variant status is now 'Not Active' and this product cannot be sold in your store.
Simply update the product variant status to active if you need to start selling it in your store again.
