NAV_HORIZ_DD:ID,Ebenentiefe

Horizontale Navigation mit drop-down Mechanismus. Es wird kein JS verwendet!

Eine modifizierte Navigation von O.G.s {NAVI}. (Sehr beeindruckend). Ich würde diese Navigation der NAV_LIST_UL:HCSS immer vorziehen.
Hier das Original von Stu Nicholls: A simple six level drop-down menu with overlap and overrun → Nutzungsbedingungen beachten :!:

{NAV_HORIZ_DD:ID,Ebenentiefe} (NAVi HORIZontal Drop Down) V1.0 28.04.08

Docu: –
Forum: http://forum.phpwcms.org/viewtopic.php?p=95342#95342

Autor: K.Heermann (flip-flop) http://planmatrix.de (05.05.09)
CMS-Version: >= V1.2.8
Version: V1.0 28.04.08
Update Version: V1.01 04.09.2010
- Der Link “Home” kann wahlweise dargestellt werden (Im PHP-Script ein/ausschalten).

Bedingung: → /config/phpwcms/conf.inc.php

$phpwcms['allow_ext_render'] = 1;

Möglichkeiten:

Sechs Ebenenen tief
Überlappen und Überfahr(rahm)en !!!
Start-ID im RT
Max Leveltiefe im RT (seit 28.04.08)
Aktiver Pfad wird für die erste Ebene gekennzeichnet
Jedes li hat eine eigene Klasse (optional)
Home kann dargestellt werden (optional in V1.01 seit 04.09.10)
Einfache html Tags in der Kategorieüberschrift wie [i] [b] [u] [s]

Installation:

Kopieren der beiden Skripte in die jeweils angegebenen Dateien (müssen angelegt werden)
1. /template/inc_script/frontend_render/rt_nav_horiz_drop_down.php
2. /template/inc_css/nav_horiz_drop_down.css
Platzieren des Tags an die Stelle in der Vorlage, an der das Menü erscheinen soll
- Z.B.: <div id=“menu_container”>{NAV_HORIZ_DD:0,4}</div>
Einbinden der CSS-Datei in die Vorlage
- ADMIN → Vorlage → CSS-Datei: [nav_horiz_drop_down.css] auswählen (Mehrfachauswahl mit <Strg> linke Maustaste)
Den Tag einstellen (Anfangs-ID und darzustellende Ebenentiefe)
- Z.B. {NAV_HORIZ_DD:2,5} (Beginnend in der Ebene mit der ID 2, Darstellung von max. 5 Ebenen in der Tiefe)
CSS-Datei anpassen

TAG

{NAV_HORIZ_DD:ID,Ebenentiefe} → z.B. Menü beginnt ab Level 0 (Home) und ist tiefenbegrenzt auf zwei Level.

<div id="menu_container">
  <div id="pmenu">{NAV_HORIZ_DD:0,2}</div>
</div>

Gegebene Struktur in dem Beispiel:

- root         (index.php  ID=0)
--- Home
--- Ebene01
--- Ebene02
--- Ebene03
--- Ebene04
--- Ebene05

V1.0:

Es wird im Artikel von root nach home weitergeleitet (permanent 301).
- Weiterleitung [index.php?home]

V1.01:

Weiterleitung von root nach home nicht notwendig, im Script kann der Link ein/ausgeschaltet werden (in ==== Custom var ====)
Generierter code: <li id="cat-id_0" class="drop home"><a class="first" href="....
