I am using Magento 2.2.2
I have an attribute called "Brand" and input type for this attribute is multiple select. In this attribute, I have set "Small Image" in additional settings for one of the values. Please refer below screenshots.
I have set the value "Test1" in one of the products. so, I want to display a small image(see second screenshot) of this attribute value in listing page. So, how can I achieve this?
