导读：dedecms是支持二级菜单了,但是我们需要分开来做,现在我们稍加改一下就可以实现调用时不需要知道ID即可根据大类小子类了,具体如下. 例子1,修改channelartlist.lib.php,代码如下: if($typeid==0 || $typeid==top) { $tpsql = reid=0 AND ispart2 AND ishidden1

dedecms是支持二级菜单了,但是我们需要分开来做,现在我们稍加改一下就可以实现调用时不需要知道ID即可根据大类小子类了,具体如下.

例子1,修改channelartlist.lib.php,代码如下:

if($typeid==0 || $typeid=='top') {
        $tpsql = " reid=0 AND ispart<>2 AND ishidden<>1 AND channeltype>0 ";
    }
//修改为:
if($typeid=='tops') {
        $tpsql = " reid=0 AND ispart<>2 AND ishidden<>1 ";
    }elseif($typeid==0 || $typeid=='top') {
        $tpsql = " reid=0 AND ispart<>2 AND ishidden<>1 AND channeltype>0 "; //开源软件:Cuoxin.com
    }
然后页面调用如下代码:

{dede:channelartlist typeid='tops' row=10}
     <li>
        <a href="{dede:field.typeurl/}">{dede:field.typename/}</a>
                <ul>
                  {dede:channel row='10'}
                        <li><a href='[field:typeurl/]' [field:rel/]>[field:typename/]</a></li>
                    {/dede:channel}
        </ul>
     </li>
{/dede:channelartlist}
例子2,首先在你的css里面加入如下代码:

*
{
    PADDING-BOTTOM: 0px; MARGIN: 0px; PADDING-LEFT: 0px; PADDING-RIGHT: 0px; PADDING-TOP: 0px
}
A {
    text-decoration:none;
}
DIV {
    WORD-WRAP: break-word; WORD-BREAK: break-all
}
LI {
    LIST-STYLE-TYPE: none; LIST-STYLE-IMAGE: none
}
.nav {
    MARGIN: 7px auto 0px; WIDTH: 968px; OVERFLOW: hidden
}
.nav LI {
    FLOAT: left; HEIGHT: 48px
}
.nav_left {
    WIDTH: 8px; BACKGROUND: url(img/s02.gif) no-repeat
}
.nav_center {
    WIDTH: 952px; BACKGROUND: url(img/s03.gif) repeat-x; FONT-SIZE: 16px
}
.nav_right {
    WIDTH: 8px; BACKGROUND: url(img/s04.gif) no-repeat
}
.nav_li_li {
    PADDING-RIGHT: 2px; BACKGROUND: url(img/s05.gif) no-repeat right top
}
.nav A {
    PADDING-BOTTOM: 0px; LINE-HEIGHT: 42px; PADDING-LEFT: 49px; PADDING-RIGHT: 49px; FLOAT: left; HEIGHT: 48px; COLOR: #fff; PADDING-TOP: 0px
}
.nav .nav_on {
    BACKGROUND: url(img/s06.jpg) no-repeat center top; TEXT-DECORATION: none
}
.nav A:hover {
    BACKGROUND: url(img/s06.jpg) no-repeat center top; TEXT-DECORATION: none
}
.nav_li_li DIV {
    Z-INDEX: 1000; BORDER-BOTTOM: #5970b2 1px solid; POSITION: absolute; BORDER-LEFT: #5970b2 1px solid; PADDING-BOTTOM: 5px; MARGIN-TOP: 42px; PADDING-LEFT: 5px; WIDTH: 190px; PADDING-RIGHT: 5px; ZOOM: 1; BACKGROUND: #ffffff 0px 0px; VISIBILITY: hidden; BORDER-TOP: #5970b2 1px solid; BORDER-RIGHT: #5970b2 1px solid; PADDING-TOP: 5px
}
SIZE: 12px; TEXT-DECORATION: none; PADDING-TOP: 5px
}
.nav_li_li DIV A:hover {
    BACKGROUND: #49a3ff; COLOR: #fff
}
