Different class and id on every "li"

How can I make a “ul” block in which to have the possibility to change the class and id on every “li” .
I already created a custom unordered list with class and id as settings, but if I have these settings just once , and it takes it for all “li”.

Sorry for the delayed response. The list input doesn’t support adding per item settings. You could use a repeater instead if your use case demands it, or perhaps you can do something based on the idx placeholder in your template if all you want is a unique ID/class.
