Question

您好我想知道这是否可行。我有一个使用带子菜单的CSS创建的水平菜单，它工作得很好。但是，我希望子菜单右侧出现子菜单。

代码是：

/*First reset ul styles*/
    .nav,
    .nav ul,
    .nav li,
    .nav a {
        margin: 0;
        padding: 0;
        border: none;
        outline: none;
    }

/*Now add fixed width & height to the menu along with rounded corners and gradients*/
    .nav {
    height: 50px;
    width: inherit;
    margin: 10px;


    background: -webkit-linear-gradient(top, rgb(198,56,32) 0%, rgb(127,48,35) 100%);
    background: -moz-linear-gradient(top, rgba(198,56,32,1) 0%, rgb(127,48,35) 100%);
    background: -o-linear-gradient(top, rgb(198,56,32) 0%, rgb(127,48,35) 100%);
    background: -ms-linear-gradient(top, rgb(198,56,32) 0%, rgb(127,48,35) 100%);
    background: linear-gradient(top, rgb(198,56,32) 0%, rgb(127,48,35) 100%);

    -webkit-border-radius: 15px;
    -moz-border-radius: 5px;
    border-radius: 5px;


    }


/*Float links left to align links horizontally & position relative to align submenus properly*/

    .nav li {
    position: relative;
    list-style: none;
    float: left;
    display: block;
    height: 50px;
    }


/* 
Styling menu links -
font, color, padding, etc. Then a dark text shadow and a color transition to create a smooth effect when the color changes on hover state. To create the links separator add a border to the left and right and then we will remove the left border from the first link and the right border from the last link. For the hover state we will only change the text color.
 */

    .nav li a {

border-bottom: none;                    

        background: none;
        display: block;
        padding: 0 14px;
        margin: 6px 0;
        line-height: 32px;
        text-decoration: none;

        border-left: 1px solid #393942;
        border-right: 1px solid #4f5058;

        font-family: Verdana, sans-serif;
        font-weight: bold;
        font-size: 14px;

        color: #f3f3f3;
        text-shadow: 2px 3px 0px rgba(0,0,0,0.6);

        -webkit-transition: color .2s ease-in-out;
        -moz-transition: color .2s ease-in-out;
        -o-transition: color .2s ease-in-out;
        -ms-transition: color .2s ease-in-out;
        transition: color .2s ease-in-out;
    }

    .nav li:first-child a { border-left: none; }
    .nav li:last-child a{ border-right: none; }

    .nav li:hover > a { 
        color: rgb(114,163,45); 
        background: none;
        font-size: 18px;
    }

/* 
SUB MENU 1
We will start to position the sub menu 50px from the top and 0px from the left of the menu item and add bottom rounded corners. We will set the opacity to 0 and on hover state to 1 to create the fade in/out effect. For the slide down/up effect we need to set the list height to 0px when is hidden and to 36px on hover state.
 */

.nav ul {

    position:absolute;

    top: 50px;
    padding-left: 0px;

    opacity: 1;
    background: rgb(43,35,34);

    -webkit-border-radius: 0 0 5px 5px;
    -moz-border-radius: 0 0 5px 5px;
    border-radius: 0 0 5px 5px;

    -webkit-transition: opacity .25s ease .1s;
    -moz-transition: opacity .25s ease .1s;
    -o-transition: opacity .25s ease .1s;
    -ms-transition: opacity .25s ease .1s;
    transition: opacity .25s ease .1s;
}

.nav li:hover > ul { opacity: 1; }

/* Hiding submenu 1 */
.nav ul li {
    height: 0;
    overflow: hidden;
    padding: 0;

    -webkit-transition: height .25s ease .1s;
    -moz-transition: height .25s ease .1s;
    -o-transition: height .25s ease .1s;
    -ms-transition: height .25s ease .1s;
    transition: height .25s ease .1s;
}
/* When hovered over, show submenu 1 */ 
.nav li:hover > ul li {
    height: 46px;
    overflow: hidden;
    padding: 0;

    z-index: 8999;
}
/* Hiding submenu TWO */
.nav ul ul li {
    height: 0;
    overflow: hidden;
    padding: 0;

    -webkit-transition: height .25s ease .1s;
    -moz-transition: height .25s ease .1s;
    -o-transition: height .25s ease .1s;
    -ms-transition: height .25s ease .1s;
    transition: height .25s ease .1s;
}
/* When hovered over, show submenu 1 */ 
.nav li:hover > ul ul li {
    height: 80px;
    padding: 0;

    z-index: 9000;
}



/* Setting width of submenu to 100px & add a bottom border instead of left and right ones 
(also removing it from last link)   */

.nav ul li a {
    width: 250px;
    padding: 4px 0 4px 40px;
    margin: 0;


    border: none;
    border-bottom: 1px solid #343438;
}

.nav ul li:last-child a { border: none; }

我会推荐Son of Suckerfish下拉（CSS解决方案）。

你可以试试这个

.menus {
    width:100px;
    height:50px;
    border: 5px solid #000000;
    border-radius: 25px;
    text-align: center;
    line-height: 50px;
    color: black;
    background-color: #dcdcdd;
}
.submenus {
    margin-top:10px;
    display:none;
    width:100px;
    height:50px;
    border: 5px solid #000000;
    border-radius: 25px;
    text-align: center;
    line-height: 50px;
    color: black;
}
#menu1outer:hover #submenus1 {
    display: block;
}
