Collapse and expand of items in sidebar do not work correctly.

[vivekragunathan]

Except for the Prologue and Help items in the sidebar, rest of the items added do not collapse and expand correctly. I expect only one item to be expanded at a given time (the one I clicked on). However, the items expand/collapse errantly.

You can reproduce the issue in action here.

Here is a demo:

[h-enk]

In ./config/_default/menus/menus.en.toml, make sure to set identifier, like so e,g,:

[[docs]]
  name = "Bash"
  weight = 30
  identifier = "bash"
  url = "/docs/bash/"

And, make sure to match the (correct) identifier in the front matter of a docs page, like so, e.g.:

..
menu:
  docs:
    parent: "bash"
weight: 310
toc: true

Works now beautifully .... Thanks
