老板的奇思妙想:下拉菜单中嵌套二级菜单

[shzrxml]

下拉菜单中嵌套二级菜单
意思是在下拉菜单中实现二级菜单的功能,就像普通的下拉菜单一样.

[bananasmiling]

你这个在网上找一下多的是..
不要到这里面来问的.

[shzrxml]

感谢大家的关心!!!

刚才看了awaysrain(绝对零度)(明天会更好)前辈的代码,十分佩服.

但小弟的意思与前辈依然不同

大家一定听说过"微软式下拉菜单",我想做的是实现类似的样式(包含二级菜单),但同时又是select的功能.例如点击IE上的"文件",然后跳出"新建"等,鼠标移到新建上,又有二级菜单弹出,现在要做的是把一级菜单(文件)变成SELECT.

密切关注哦!!!

那得用div模拟了

select实现不了

[研究汽车的米舞指]

可以肯定用select实现不了那样的样式。

[qxs]

很麻烦的，用FLASH做

[nchen123]

你想要的是这样的吧？

[shzrxml]

hehe, 没说清楚
我所指的下拉菜单是

<select name="D1" onChange="submit()">
<option>1</option>
<option>2</option>
</select>

这样的菜单可否实现!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!

[awaysrain]

模拟吧，用select不行

[cdsun]

select不行


bananasmiling(hello找我)
这个兄弟啊，我为搂主说句话啊，你也别生气

别人有问题来这里问你为什么不让别人问呢？我觉得你说得很奇怪啊。别人都不问你的三角从哪里来？

[angeldjd]

DW有插件做下拉菜单用的，特简单。。找不到的话管我要。[e-mail]

[甘泉123]

老板有前途~~

[研究汽车的米舞指]

我们都没看过select里面镶嵌select的。
不过我想你老板可能只是想实现某个功能，是不是你下拉菜单项目太多，而且是项目下有子项目的，你可以考虑用树状结构实现。

还有问题，自己修改吧
