Help:Tabber

This extension is enabled by default on Fandom.

Tabber allows you to add multiple tabs to a section of content, which can be toggled without having to reload the page.

Step-By-Step

Open an article for editing and switch to Source mode.

Copy and paste the following code into your editor.

<tabber>First Tab Title=First tab sample text.
|-|Second Tab Title=Second tab content goes here. 
|-|Third Tab Title=Third tab content goes here.
</tabber>

Click "Preview". You'll see that the code produced these tabs:

First tab sample text.

Second tab content goes here.

Third tab content goes here.

Click "Back" to return to editing.

Edit your tabs by replacing the text of the titles and content with your community's content. For example, replace with "First Tab Title" with "Characters," and replace the sample text with descriptions and images of your favorite characters. You can also change the number of tabs by adding or removing code.

Usage Information

Formatting: Keep in mind that the title should always end with an equal sign ("="), and the tab separator ("|-|") must always appear between tabs.

Wikitext: You can use any wikitext within your tabs, including templates and images.

Headers: H2 and H3 headers are disabled by default in Tabber. You can enable them by adding the following code to MediaWiki:Wikia.css (and MediaWiki:Monobook.css if you wish to show them in the Monobook skin as well):

.tabberlive .tabbertab h2,
.tabberlive .tabbertab h3 {
    display:block !important;
}

Tabview and Tabber: Tabber tags can be used within another tabber. Tabber tags will not work in the tabview tags; the text inside of the tabber will render as several paragraphs.

Styling

.tabberlive {
	/* tabber wrapper style */
}
.tabberlive > .tabbertab:not(.tabbertabhide) {
	/* tabber visible content */
}
.tabberlive > .tabbernav > li > a {
	/* tabber tabs */
}
.tabberlive > .tabbernav > li > a:hover {
	/* tabber tabs when being hovered */
}
.tabberlive > .tabbernav > li > a:active {
	/* tabber tabs when being clicked */
}
.tabberlive > .tabbernav > li.tabberactive > a {
	/* selected tabber tab */
}
.tabberlive > .tabbernav > li.tabberactive > a:hover {
	/* selected tabber tab when being hovered */
}
.tabberlive > .tabbernav > li.tabberactive > a:active {
	/* selected tabber tab when being clicked */
}

Issues

Broken Mobile Experience

A lot of the CSS and JavaScript that runs on your desktop/laptop cannot on a mobile device, at least, without slowdowns. To counter this, FANDOM has removed most of that code from the mobile skin - including the stuff that makes Tabber possible. As a result, mobile users won't see any of the visual cues that separate each set of information.

You can work around that with code like the following:

==This section has tabs!==
<tabber>
|-|First=<h3 style="display:none">First</h3>Lorem ipsum dolor sit amet...
|-|Second=<h3 style="display:none">Second</h3>Lorem ipsum dolor sit amet...
|-|Third=<h3 style="display:none">Third</h3>Lorem ipsum dolor sit amet...
</tabber>

...but there are problems with this method as well (complex HTML, inline CSS, etc.). You could write a template or module to automatically do that, but no amount of trickery can solve the fundamental problems with tabs (see next section). Besides, that's a lot of effort for very little gain; you might as well just use ordinary sections instead.

View/Edit Tab Content

Tabber does not provide a simple way to view/edit the original page. This can be troublesome for inexperienced users that want to edit the content inside a tab. Additionally, people who use the VisualEditor will be unable to edit it without switching to source mode.
