[chengleqi]

Describe the feature you want

• I drew a flowchart, it can be shown correctly in the Mermaid v8.11.2 Live Editor, but when I copy the mermaid code into the {{< mermaid >}} {{< /mermaid >}} shortcode , I got nothing on hugo server preview. Then I found the flowchart can only be used in hign version https://mermaid-js.github.io/mermaid/#/flowchart?id=beta-flowcharts, mermaid released v8.11.2 3 days ago, but Feelit theme use v8.5.1. I'm not familiar with front end.I don't know how to update the version myself.Could you update the version of mermaid, please.

First of all I had plans to update the mermaid version which I was doing on PR #54, but I had to put it on hold due to some broken internal API calls mentioned in mermaid issues #1034 which is effected on the dark-theme mode.

About the flowchart issue, it should work with the current version 8.5.1 theme-documentation#flowchart.

I tried again but it still couldn't be shown with the current version 8.5.1

Hmm, seems like you were right.

If you are really need it ASAP you can apply the temporary workaround from #54 (All things good with your Flowchart code)
