1 Horizontales Akkordeon mit Boardmitteln (MooTools)

Horizontales Akkordeon mit Boardmitteln (MooTools)

Ziel

Hohe schmale Akkordeon-Reiter stehen vertikal nebeneinander, und die Inhalte öffnen sich horizontal nach rechts.

Gestestet auf Windows XP mit

FF 25.0.1
Chrome 31.0
Opera 12.16
Safari 5.1.7
IE7/8

Umsetzung

Template moo_accordion_horizontal.html5 als Kopie von moo_accordion.html5 erstellen und im Layout anstatt moo_accordion auswählen. CSS-Datei accordion.css erstellen und im Layout einbinden.

Das Template

MooTools' Fx.Accordion bietet von Haus aus die Möglichkeit, anstatt der Höhe, die Breite der sich öffnenden Inhaltscontainer zu animieren. Dies wird hier genutzt.

Dazu werden die Optionen im Template geändert von

...
opacity: false,
alwaysHide: true,
...

nach

...
display: 0,        // open first content element
opacity: false,    // do not animate opacity (maybe there's a bug, as opacity is animated anyway)
alwaysHide: false, // don't close all content elements, it may look ugly for horizontal accordions
width: true,       // animate the width
height: false,     // don't animate the height
fixedWidth: 777,   // set the width of the opening content element
...

Hier das komplette angepasste Template für Contao 3.2.1

<script>
  (function($) {
    window.addEvent('domready', function() {
      new Fx.Accordion($$('div.toggler'), $$('div.accordion'), {
        display: 0,
        opacity: false,
        alwaysHide: false,
        width: true,
        height: false,
        fixedWidth: 777,
        onActive: function(tog, el) {
          el.setProperty('aria-hidden', 'false');
          tog.addClass('active');
          tog.getNext('div').fade('in');
          tog.setProperty('aria-expanded', 'true');
          return false;
        },
        onBackground: function(tog, el) {
          el.setProperty('aria-hidden', 'true');
          tog.removeClass('active');
          tog.getNext('div').fade('out');
          tog.setProperty('aria-expanded', 'false');
          return false;
        }
      });
      $$('div.toggler').each(function(el) {
        el.setProperty('role', 'tab');
        el.setProperty('tabindex', 0);
        el.addEvents({
          'keypress': function(event) {
            if (event.code == 13) {
              this.fireEvent('click');
            }
          },
          'focus': function() {
            this.addClass('hover');
          },
          'blur': function() {
            this.removeClass('hover');
          },
          'mouseenter': function() {
            this.addClass('hover');
          },
          'mouseleave': function() {
            this.removeClass('hover');
          }
        });
      });
      $$('div.ce_accordion').each(function(el) {
        el.setProperty('role', 'tablist');
      });
      $$('div.accordion').each(function(el) {
        el.setProperty('role', 'tabpanel');
      });
    });
  })(document.id);
</script>

CSS

Das CSS enthält jeweils 3 Blöcke (Zum Testen kann ein Block durch entfernen des letzten Slashes "/" in der Überschrift deaktiviert werden). Dabei bedeutet:

mandatory = Pflicht
recommended = empfohlen
custom = eigenes Design

Im endgültigen CSS sollten die Selektoren zusammengefasst werden, z.B. die ".toggler". Sie sind hier nur wegen ihrer unterschiedlichen Wichtigkeit separiert.

Um die Größenverhältnisse anzupassen finden sich im CSS folgende Werte

Gesamthöhe = 333px
Togglerbreite = 55px
Inhaltsbreite = 777px

Wo man diese Werte findet muss man sie mit seinen eigenen Größen ersetzen (auch bei transform: matrix...). Im Template muss man für die Option fixedWidth den Wert der Inhaltsbreite angeben.

Das CSS beschränkt sich auf moderne Browser, damit es übersichtlicher und leichter nachzuvollziehen ist. Unter den Punkten Alte Browser findet man das CSS, welches für Browser bis runter zu IE7 zusätzlich geladen werden muss.

Version 1

Anm. box-sizing wird von FF 25.0.1 immer noch nicht unterstützt. Deswegen auch hier der Präfix -moz-.
