超级鱼菜单垂直向左打开？

[英]Superfish menu vertically and opening to the left?

问题描述

我正在尝试垂直使用Superfish，但要与页面右侧对齐，从而在左侧打开任何子菜单。 我一直在调整一些CSS属性来实现此目的，但是它不能完美地工作-箭头始终位于任何父菜单文本的右侧，在这种情况下，箭头应位于文本的左侧，子菜单应位于左侧在2级和3级中的工作方式并不完全相同！

这真让我抓狂！ 任何人都可以完美地完成这项工作吗？ 有技巧或例子吗？

预先感谢，LM

我设法将箭头放在左侧（在CSS中注释[大写的我的编辑：...]），并且还设法在左侧打开了子菜单（使用最新的SuperFish版本，带有.sf-vertical类），但是我仍然有第三级子菜单的问题-阴影放错了位置！

这是我更改过的html页面和CSS代码（“ superfish.css”中的箭头和“ superfish-vertical.css”中的位置：

superfish.css 

/*** ESSENTIAL STYLES ***/
.sf-menu, .sf-menu * {
    margin: 0;
    padding: 0;
    list-style: none;
    font-family: Arial, Helvetica, Sans-Serif; font-size: 12px; color: #FFFFFF;
}
.sf-menu li {
    position: relative;
}
.sf-menu ul {
    position: absolute;
    display: none;
    top: 100%;
    left: 0;
    z-index: 99;
}
.sf-menu > li {
    float: left;
}
.sf-menu li:hover > ul, .sf-menu li.sfHover > ul {

}

.sf-menu a {
    display: block;
    position: relative;
}
.sf-menu ul ul {
    top: 0;
    left: 100%;
}


/*** DEMO SKIN ***/
.sf-menu {
    float: left;
    margin-bottom: 1em;
}
.sf-menu ul {
    box-shadow: 2px 2px 6px rgba(0,0,0,0.2);
    min-width: 12em; /* allow long menu items to determine submenu width */
    *width: 12em; /* no auto sub width for IE7, see white-space comment below */
}
.sf-menu a {
    /*border-left: 1px solid #fff;*/
    border-top: 1px solid #dFeEFF; /* fallback colour must use full shorthand */
    border-top: 1px solid rgba(255,255,255,0.5);
    padding: .75em 1em;
    text-decoration: none;
    zoom: 1; /* IE7 */
}
.sf-menu a {
    color: #13a;
}
.sf-menu li {
    background: #BDD2FF;
    white-space: nowrap; /* no need for Supersubs plugin */
    *white-space: normal; /* ...unless you support IE7 (let it wrap) */
    -webkit-transition: background .2s;
    transition: background .2s;
}
.sf-menu ul li {
    background: #AABDE6;
}
.sf-menu ul ul li {
    background: #9AAEDB;
}
.sf-menu li:hover, .sf-menu li.sfHover {
    background: #CFDEFF;
    /* only transition out, not in */
    -webkit-transition: none;
    transition: none;
}

/*** arrows (for all except IE7) **/
.sf-arrows .sf-with-ul {
    padding-right: 2.5em;
    *padding-right: 1em; /* no CSS arrows for IE7 (lack pseudo-elements) */
}
/* styling for both css and generated arrows */
.sf-arrows .sf-with-ul:after {
    content: '';
    position: absolute;
    top: 50%;
    left: 2px; /* MY EDIT: PLACES ARROWS AT MOST LEFT, IT WORKS OK */
    margin-top: -3px;
    height: 0;
    width: 0;
    /* order of following 3 rules important for fallbacks to work */
    border: 5px solid transparent;
    border-top-color: #dFeEFF; /* edit this to suit design (no rgba in IE8) */
    border-top-color: rgba(255,255,255,0.5);
}
.sf-arrows > li > .sf-with-ul:focus:after,
.sf-arrows > li:hover > .sf-with-ul:after,
.sf-arrows > .sfHover > .sf-with-ul:after {
    border-top-color: white; /* IE8 fallback colour */
}
/* styling for right-facing arrows */
.sf-arrows ul .sf-with-ul:after {
    margin-top: -5px;
    margin-right: -3px;
    border-color: transparent;

    border-left-color: rgba(255,255,255,0.5);
}
.sf-arrows ul li > .sf-with-ul:focus:after,
.sf-arrows ul li:hover > .sf-with-ul:after,
.sf-arrows ul .sfHover > .sf-with-ul:after {
    border-left-color: white;
}

最后是superfish-vertical.css 

/* adding sf-vertical class in addition to sf-menu creates a vertical menu */
/* eg. <ul class="sf-menu sf-vertical"> ... */
.sf-vertical {
    width: 150px;
/* If you want the width of the closed menu to expand to its
widest top-level menu item (like its "Supersubs" submenus do),
replace the width rule above with the following two rules. */

/*
min-width: 12em;
*width: 12em;
*/
}

.sf-vertical ul {
    left: -100%; /* MY EDIT: THIS WORKS OK AT 2nd LEVEL */
    top: 0;
}
.sf-vertical > li {
    float: none;
}
.sf-vertical li {
    width: 100%;
}

.sf-vertical ul ul li {
    left: -200%; /* MY EDIT: THIS WORKS OK AT 3rd LEVEL BUT SHADOW IS MISPLACED */
    top: 0;
}

/*** alter arrow directions ***/
.sf-vertical.sf-arrows > li > .sf-with-ul:after {
    margin-top: -5px;
    margin-right: -3px;
    border-color: transparent;
    border-left-color: #dFeEFF; /* edit this to suit design (no rgba in IE8) */
    border-left-color: rgba(255,255,255,0.5);
}
.sf-vertical.sf-arrows li > .sf-with-ul:focus:after,
.sf-vertical.sf-arrows li:hover > .sf-with-ul:after,
.sf-vertical.sf-arrows .sfHover > .sf-with-ul:after {
    border-left-color: white;
}

您的第二个选择器正在选择<li>而不是<ul> （阴影在此处），尝试； 

.sf-vertical ul ul { /* removed trailing "li" selector */
    left: -100%; /* changed from 200% */
    top: 0;
}

这个问题可能很老了，但是可能会有所帮助，请尝试使用jsfiddle 。 

(function($) { //create closure so we can safely use $ as alias for jQuery
    $(document).ready(function() {
        // initialise plugin
        var example = $('.sf-menu').superfish({
            //add options here if required                  
        }).supposition();
    });
})(jQuery);
