Collapsing a text-only sidebar group hides its own title

[paulhibbitts]

Description

Collapsing a root sidebar group with a text-only title hides the title itself, not just its nested links - leaving no way to re-expand it without reloading the page.

Expected behavior

Collapsing the group should hide only its nested list. The group's own title should stay visible and clickable so it can be expanded again.

Actual behavior

Clicking a text-only group title to collapse it hides the group's title along with its nested links. Since the title itself disappears, there's no way to click it again to re-expand - the whole group is effectively gone until the page reloads.

Steps to reproduce

1. Enable the new sidebar-groups feature and use a _sidebar.md where a root group's heading is plain text with no link (not a heading that's itself a page link):

   - Topic
     - [Page One](page-one.md)
     - [Page Two](page-two.md)

2. In index.html:

   window.$docsify = {
     loadSidebar: true,
     collapsibleSidebarGroups: true,
   };

3. Click "Topic" in the sidebar to collapse it

Environment

I can't reproduce this issue.

This should be fixed now. Have you tried the latest “develop” version?

	// Preserve the original styling behavior: only text-only paragraphs
