Have you provided an initial effort estimate for this issue?

I am not a FlowFuse team member

Is there a reason for putting the markdown in a template, and not just in the markdown node itself?

[buschhardtt]

No, but I use the markdown node. See

"id": "c61f4317ad20f535",
"type": "ui-markdown",...

I have a complete markdown string from somewhere (e.g. database) and would present that on dashboard. Is this possible? Thank You

[joepavitt]

Yep, you can just do:

{{ msg?.payload }}

in your Markdown template, pass the markdown via msg.payload and it'll render. See Docs

Hello Joe, I use @flowfuse/node-red-dashboard 1.13 and it will not run.

1. I have a Input-Node with a string put in msg.payload-> # markdown header\n## secondheader\n\nmytext
2. the Markdown-Node show me the String but not the Markdown The same result, when I use a Template-Node (for the linefeed). Maybe the Linefeed is the problem? How must the String formated to show correct in the Markdown-Node

Thank You very much

[joepavitt]

Thanks for the extra detail @buschhardtt - remembering now that we have an issue with rendering injected markdown: https://github.com/FlowFuse/node-red-dashboard/issues/615

I'll get @gayanSandamal to take a look at this more actively, as fixing this would close out both issues, and make ui-markdown considerably more useful.

The challenge is, we run the content through the markdown parser first, then any injected content (which can come at any time) is placed into the {{ }} placeholders, but not re-parsed again
