Thank you for your quick response and your advice.
You are probably right about rethinking my data architecture, but let me explain why I thought that I might need this conversion.
Let’s have as an example the description of Car#30 in your demo site https://cars.wp-filter.com/. I would like to be able to click on the word “Petrol” and have a list of all the cars whose fuel type is “Petrol” or click on the word “Sedan” and a list with the Sedan cars be displayed etc. Being a newbie in WordPress, I couldn’t accomplish it and that’s the reason I formulated the previous question.
