List of string on dashboard

Hi all, I'm working with dashboard and I would like create a text output of a payload composed by many string. Each string had to be shown in different lines. it is possible?

Yes it is -- once you understand that Dashboard uses Angular to generate HTML elements, you can use many techniques e.g. put your multi-line text inside <pre> tags, or use CSS styling to show a pre-formatted paragraph, or replace newlines with <br> tags, etc.

Check out this old post for some other ideas.

Hello
take a look at this sample flow and check if it works for you.
If you need your log to persists restarts, you'll need to use persistent context.

I got this flow in this forum not long ago, but I don't know who is the original author.
Sorry for not giving credit.
