Module:NavboxMobile

From Ikwipedia
Revision as of 07:07, 24 November 2024 by EnWikiAdmin (talk | contribs)

This module implements the {{Navbox}} template for mobile devices when Extension:MobileFrontend is installed. This mobile version differs from the desktop version as follows:

  • The table does not collapse.
  • The list cells, e.g. group1, list1, each display across the width of the screen
  • Images are not displayed, as it increases the complexity of the layout while reducing the area needed for content.

Original from wikipedia::Module:User:Lady G2016/NavboxMobile/doc

Overview

This approach works by utilizing CSS class rules. See: Hiding content on desktop devices

An onlymobile class in MediaWiki:Common.css will not display classes intended for mobile devices.

A nomobile class in MediaWiki:Mobile.css will not display classes intended for desktop devices.

Use these classes together inside the same template. The template will be rendered twice, but only display once depending on the view (desktop or mobile).

Module description

The module was copied from Module:Navbox and modified as follows:

  • All instances of navbox- were replaced with navboxMobile- to provide unique CSS identifiers that are independent of navbox.
  • All statements which processed images were removed. The statements remain as comments to show what was changed.

In function renderListRow(), the cell pair of (groupCell, listCell) appearing as a single row is broken into separate rows by adding local row = addTableRow(tbl) just before listCell.

Adding this row and removing the images are the only functional changes made to the existing navbox template. Except for removal of the images, the parameters used in the current navbox are supported.

Implementation

MediaWiki:Common.css

In MediaWiki:Common.css, add: 

/* Only for mobile devices */
.onlymobile {
display:none;
}

MediaWiki:Mobile.css

In MediaWiki:Mobile.css, add: 

/* Only for desktop devices */
.nomobile {
display:none;
}

MobileFrontend processes MediaWiki:Mobile.css. To provide an independent class that is not affected by the navbox rules, copy all of the navbox and hlist CSS styles from MediaWiki:Common.css to MediaWiki:Mobile.css.

Replace all navbox- with navboxMobile-. For example, navbox-title becomes navboxMobile-title. This will match the CSS properties in Module:NavboxMobile.

An example page can be found at User:Lady G2016/MediaWiki:Mobile.css.

Template:Navbox

Modify Template:Navbox to call both the desktop and mobile Lua modules as follows: 

<div class="nomobile">{{#invoke:Navbox|navbox}}</div><div class="onlymobile">{{#invoke:NavboxMobile|navboxMobile}}</div><noinclude>
{{Documentation}}
</noinclude>

This will render both the desktop (navbox) and mobile (navboxMobile) versions. When displaying from a desktop view, MediaWiki:Common.css will not display the mobile template. When displaying from a mobile, only the mobile template will be displayed.

Constraints and limitations

This template was developed with MediaWiki 1.27.4 (Long Term Support) and MobileFrontEnd 1.0.0 (29 June 2016). No testing was performed with other versions.

The navbox class is explicitly disabled in /extensions/MobileFrontend/resources/skins.minerva.content.styles/hacks.less. Attempts to override navbox using $wgMFRemovableClasses do not display as intended when the navbox class is enabled.
