Hi @msbt, rough draft of the navigation similar to our main site. I'm not really familiar with all the css in our docs, it's split into a couple of files so I mostly made new classes. Let me know if I should shuffle some stuff elsewhere. Thanks!

[amotl]

Thanks. Isn't this supposed to go into some SSI snippet?

[matkuliak]

Not sure. After pushing, @msbt let me know about https://cratedb.com/_hcms/api/navi-header. That was previously used as a dynamic source for the list through ESI. So going to switch to that probably

[amotl]

Can you add this to https://cratedb.com/_hcms/api/navi-header instead, @msbt? 🙏

[msbt]

@amotl I'll give it a go, might take some time though

@amotl I've implemented the current navigation as fallback and reintroduced the esi's, are we happy with it? PR link is to the latest status (https://crate-docs-theme--534.org.readthedocs.build/en/534/)

I guess it will be good to merge and release, and applying "ack by timeout" will not cause too much harm, even despite its duration was a bit short here. If other reviewers can spot any annoyances, or wish to add more items, relevant suggestions will be considered in retrospective.
