Convert meta-values into taxonomy terms

Hello

I think yes, but not sure why you need it + for such operation should be created custom script on php.

But better rethink your site data-architecture to avoid of mess of data …

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.

Hello

I think its possible! But you will need make that buttons self to make them clickable OR attach click event on each gray button as is using jQuery, and link you can create using: https://wp-filter.com/document/constant-link-extension/
