Now click on Addons.

After that, click on Create New Addon
After that, the vendor will get all the options previously discussed for creating Product Addon. You can see that from the below GIF. Lastly, click on Publish to finish.
That is it for vendor creating Product Addon.
Note: For the customers, they have to click on the product to get the Addons option.
So far, the addons we have created was global addons. That means that addon was applicable to all the products. But there is an option for creating addons for an individual product as well.
To do that, just go to the Edit page of the product. Then scroll down. you will find the Addon option. There you will find the Addon option. Edit those options to make an individual addon for that particular product.
Points to Remember
If a vendor or admin create an Addon, that Addon will be applicable only for that store of vendors or admins. However, an admin can view all the addons created by all the vendors. But vendors can only view their own addons, they can not view the addons of other vendors.
That is it for Product Addons. Enjoy!
