Default style for drop-down list:


Here are two ways to customize a drop-down list:

Method One:

Customize the style of the drop-down list with a pure CSS.

Principle: Clears the Default drop-down list style, customizes the style, and attaches a small arrow right-aligned picture.

<!doctype html>



Problem: Modify the width and height of option to be invalid.


Method Two:


Use P+ul+jquery to implement a custom style drop-down list select.




HTML code:


<p id= "container" ><form action= "" method= "post" ><p><ul><li class= "active" > Please select </li ><li> Beijing </li><li> Shanghai </li><li> Guangzhou </li></ul></p></form> </p>


CSS code:


#container {background:grey;width:300px;height:200px;padding:20px;} Form p{    width:236px;    height:34px;} Form P{font-family:microsoft Yahei;    Background: #FFFFFF;} Form p:hover{    border:1px solid #E74F4D;} Form ul{margin:0;padding:0;} Form ul li:first-child{    height:34px;    line-height:34px;} Form ul li{    width:236px;    height:24px;    line-height:24px;    font-size:15px;    Color: #323333;    opacity:0.7;    Background: #e3e3e5;    Text-indent:12px;display:none;} Form ul li.active{    Display:block;    Background:url ("Images/arrows_active_down.gif") no-repeat scroll right center;    Opacity:1;} Form UL Li:not (. Active): hover{    background: #E74F4D;    Color:white;}


jquery Code:


$ (document). Ready (function () {var p = $ ("form"). Find ("P");        P.mouseover (function (e) {var event = e | | window.event; var target = Event.target | |        Event.srcelement;        var _this = $ (this);            if (target.nodeName.toLowerCase () = = ' Li ') {_this.find (' li '). CSS (' Display ', ' block ');                _this.find (' Li '). Click (function () {var li = $ (this);            _this.find ('. Active '). Text (Li.text ());        });            } _this.mouseout (function (e) {var event = e | | window.event; var target = Event.target | |            Event.srcelement;        if (target.nodeName.toLowerCase () = = ' Li ') _this.find (' Li '). Not ('. Active '). CSS (' Display ', ' none ');    }); });});
