请教个问题关于下拉框
我的搜索页现在是这样的代码，下拉框里面可以选检索标题和智能模糊，我想把这个下拉框改成百度那样点的，就像 新闻 网页 贴吧 知道 mp3。请高手帮帮忙！
<div class="search">
<form name="formsearch" action="/plus/search.php">
<div class="form">
<h4>搜索</h4>
<input type="hidden" name="kwtype" value="0" />
<input name="q" type="text" class="search-keyword" id="search-keyword" value="在这里搜索..." onfocus="if(this.value=='在这里搜索...'){this.value='';}" onblur="if(this.value==''){this.value='在这里搜索...';}" />
<select name="searchtype" class="search-option" id="search-option">
<option value="title" selected='1'>检索标题</option>
<option value="titlekeyword">智能模糊</option>
</select>
<button type="submit" class="search-submit">搜索</button>
</div>
</form>
<div class="tags">
<h4>热门标签:</h4>
<ul>
</ul>
</div>
