I love this skin and it fits perfectly to the city week I am configuring. Yet, the search box is very small and difficult to find in the off-canvas side menu and autocomplete was not working on mobile like it does on a large screen. I tried editing pivot.skin.php and changed autocomplete="off" to "on" in lines 122 and 167 as described here, but nothing changed.
What I did instead: I added a search icon to the top bar which only appears on small screens. The icon links to Special:Search, where autocomplete is working also on mobile. Then, I deleted the search box from the off-canvas sidebar.
To add the icon, open your pivot.skin.php and look for <section id="middle-nav" class="middle tab-bar-section"> (somewhere around line 100). Directly below this line, add the following snippet:
<section id="middle-nav" class="right-small show-for-small">
<a href="/wiki/Special:Search" class="search"><span id="search-icon"><i class="fa fa-search fa-lg"></i></span></a>
</section>
The path to your Special:Search given at href="..." will vary, if your are not using short URLs with the same structure as me. This should work. If not, you can try to find a solution with the "Inspect Element" function of your browser and then copy the outer HTML to your pivot.skin.php.
To remove the search box from your off-canvas side menu on mobile only, find the following code snippet in your pivot.skin.php and delete it.
<li class="has-form">
<form action="<?php $this->text( 'wgScript' ); ?>" id="searchform" class="mw-search">
<div class="row collapse">
<div class="small-12 columns">
<input type="search" name="search" placeholder="<?php echo wfMessage( 'search' )->text() ?>" title="Search [alt-shift-f]" accesskey="f" id="searchInput-offcanvas" autocomplete="on">
</div>
</div>
</form>
</li>
Alternatively, you can add the following to your Mediawiki:Pivot.css:
.row.collapse > .column, .row.collapse > .columns {
display: none;
}
I hope this helps and works for you, too. Getting a proper solution for the search box issue in the pivot skin (hard to find, too small and no autocomplete) would nevertheless be great.
