Module:Collapsible/doc

This module is a small compatibility shim that exposes a function named collapsible. It forwards calls to an available renderer so that legacy templates using do not break.

Purpose

Some imported templates call:

or

On Chalo Chatu the primary entrypoint is main in Module:Collapsible list. This shim looks for that first; if unavailable, it may fall back to a compatible function in Module:Navbox (if present). If neither exists, it returns a clear error message.

Usage

Prefer the direct entrypoint:

Only use this shim for legacy code that cannot be edited:

Parameters

Identical to Module:Collapsible list’s main:

title / header

Heading text.

collapsed

yes / no. Adds class collapsed when yes.

1..50

Positional items.

class, id, list_style, item_style

Optional styling hooks passed through when supported.

Behavior

• If Module:Collapsible list with function main(frame) exists, all arguments are forwarded to it.
• Else, if Module:Navbox with function navbox(frame) exists, arguments are forwarded as-is (output may differ).
• Else, a readable Module error string is returned.

Migration guidance

Where possible, update templates to call:

This reduces indirection and makes behavior explicit.

Troubleshooting

• If you still see "Script error: The function 'collapsible' does not exist", ensure this page (Module:Collapsible) is created and that Module:Collapsible list exists with a main function.
• If output appears but styling looks plain, add CSS for .chalo-collapsible classes in MediaWiki:Common.css.
