Hi @novaknole , I m trying to answer those questions above based on current docsify behaviors.

1. Does docsify loads content separated from on single .md ?

Nope, docsify render the single md file to a single page in one time, there is no a simple mechanism to lazy load inside one page. Although it seems not that friendly to big content for now :( .

2. Does there has a way to make content collapsible ?

Simply, markdown supports it already. i.e.

<details>
  <summary>Click me</summary>
  
  Using `<details>` and `<summary>`
  ### How to make it collapsible
  ...

</details>

Hi @novaknole.

Have you considered breaking your "quite long" pages into separate pages and/or leveraging the sidebar for efficiently navigating between sections on each page? This seems like the most obvious solution.

Collapsable content is available today as described in @Koooooo-7's comment above.

As for lazy-loading sections of page, this may help with performance issues when loading unusually long pages but it would introduce a number of new issues to consider. My initial reaction is that tackling these issues would add quite a bit of complexity to the page rendering process. Since page rendering performance is not something we hear Docsify users complain about much, I don't see this feature being prioritized any time soon.

For now and the foreseeable future, I think your best option is to revisit your "quite long" pages and break them up into smaller, more manageable content blocks.
