defaultOpenLevel sidebar prop not working

[ZYJLiu]

To Reproduce

The sidebar tab remains closed by even though defaultOpenLevel: 1

1. Create new fumadocs project using npm create fumadocs-app

2. Create content/docs/test/test.mdx to display "test.mdx" under a "test" tab in sidebar

3. Update app/docs/layout.tsx with sidebar={{ defaultOpenLevel: 1 }}

import { DocsLayout } from "fumadocs-ui/layouts/docs";
import type { ReactNode } from "react";
import { baseOptions } from "@/app/layout.config";
import { source } from "@/lib/source";

export default function Layout({ children }: { children: ReactNode }) {
  return (
    <DocsLayout
      tree={source.pageTree}
      {...baseOptions}
      sidebar={{ defaultOpenLevel: 1 }}
    >
      {children}
    </DocsLayout>
  );
}

Current vs. Expected behavior

Currently, folders in sidebar remain closed when using defaultOpenLevel prop.

The expected behavior is that they open to the specified level.

Oh yes the initial sidebar level was mistakenly increased to 1, should be fixed now

[ZYJLiu]

defaultOpenLevel still doesn't seem to work, using 14.5.2

[fuma-nama]

The fix is on the latest version, have you updated?

[ZYJLiu]

working now with 14.5.4, ty!
