How to make a coin show in the website's Market dropdown

In the application one can add a coin from the altcoins to display under settings. What is required to display coin in the Market in bisq’s website drop down?

I assume that you can not add it or at least that it wasn’t intended for coins to be added to the drop down by the website creator.
It is most likely just how the website was built and you can’t do much about it.

I want to know how to make it like this ?
Only seeing desktop software not web based application…
Can it be doable ?

Thanks & Regards

What is your question exactly?
Are you asking for trading on the website? That would not be possible, as Bisq is decentralized, being able to trade on a website would be centralized.
