html-css-如何创建左边的子菜单

admin 118℃
嗨,我的目标是让子菜单扩展到左边而不是右边。 css如下所示,

    /*<![CDATA[*/

/* page styling, unimportant for the menu. only makes the page looks nicer */

/* - - - ADxMenu: BASIC styles - - - */

/* remove all list stylings */
.menu, .menu ul {
    margin: 0;
    padding: 0;
    border: 0;
    list-style-type: none;
    display: block;
}

/* move all list items into one row, by floating them */
.menu li {
    margin: 0;
    padding: 0;
    border: 1px solid #000000;
    display: block;
    float: left;                /* modified by poornima. (default float :right ) */
    position:relative;
    z-index:5;
}

/* define new starting point for the nested UL, thus making positioning it a piece of cake */
.menu li:hover {
    position: relative;
}

/* align the submenus with the right edge */
.menu li ul {
    right: 0;
    margin-left:-385px;       /* already setted value: -363px;*/    /* IE 7 & 8 Problem to bring the submenu for left side */
}

/* force the submenu items into separate rows, while still keeping float:left (which resolves IE6 white-gap problem) */
.menu li li {
    width: 100%;
}

/* fix the position for 2nd level submenus.
    first make sure no horizontal scrollbars are visible on initial page load by sliding them all into top-left corner  */
.menu li li ul {
    top: 0;
}

/* ...and then place the submenu where it should be when shown */
.menu li li:hover ul {
    right: 100%;
    padding-right:52px; /*Newly added property for submenu hover properly*/
}

/* initialy hide all sub menus */
.menu ul {
    visibility: hidden;
    position: absolute;
    z-index: 10;
}

/* display them on hover */
.menu li:hover>ul {
    visibility: visible;
}

/* -- float.clear -- force containment of floated LIs inside of UL */
.menu:after, .menu ul:after {
    content: ".";
    height: 0;
    display: block;
    visibility: hidden;
    overflow: hidden;
    clear: both;
}
/* IE7 float clear: */
.menu, .menu ul {
    min-height: 0;
}
/* -- float.clear.END --  */

/* sticky submenu: it should not disappear when your mouse moves a bit outside the submenu
    YOU SHOULD NOT STYLE the background of the ".menu UL" or this feature may not work properly!
    if you do it, make sure you 110% know what you do */
.menu ul {
    background-image: url(empty.gif);/* required for sticky to work in IE6 and IE7 - due to their (different) hover bugs */
    padding: 10px 30px 30px 30px;
    margin: -10px -30px 0 0;
    /*background: #f00;*/       /* uncomment this if you want to see the "safe" area. you can also use to adjust the safe area to your requirement */
}


/* - - - ADxMenu: DESIGN styles - - - */

.menu, .menu ul li {

    margin-left:22px;      /*Move menu to right side*/
    text-align:right;      /*Move menu to right side and the text align right*/
}

.menu ul>li + li {  /* and remove the top border on all but first item in the list */
    border-top: 0;

页面截图如下 alt text

当我鼠标悬停在'用户管理'菜单上时,'创建用户'必须展开到左侧。如有任何帮助,我们将不胜感激。

谢谢

您的代码上有一条注释,上面写着

/*…然后将子菜单放在显示时应该放在的位置*/

在此之后,您将获得以下信息

.menu li li:hover ul {
    right: 100%;
    padding-right:52px;
}

所以我想如果你改变 padding-rightpadding-leftright:100%left:100% 也许你可以更改菜单。

帮助您的最佳方法是,为我们提供一个有关jsbin.com
