Question

我有一个下拉表单，其宽度目前受激活下拉列表的链接宽度的限制：

the problem

我希望表单尽可能扩展到将所有表单元素放在一行上。我怎么能这样做？

当前的HTML代码：

<h1>Time Period:
    <div id="date-filter-dropdown" class="dropdown">
            <a class="dropdown-toggle" data-toggle="dropdown" href="#">
                <span class="primary">May 2013</span></a>
            <ul class="dropdown-menu" role="menu">
                <li>
                    <form class="form-inline">
                        <input type="text" class="input-mini filter-time-form" id="id_filter_form_year" maxlength="4" size="4" placeholder="YYYY" />
                        <span class="filter-form-date-dividers">&dash;</span>
                        <input type="text" class="input-mini filter-time-form" id="id_filter_form_month" maxlength="2" size="2" placeholder="MM" />
                        <span class="filter-form-date-dividers">&dash;</span>
                            <input type="text" class="input-mini filter-time-form" id="id_filter_form_day" maxlength="2" size="2" placeholder="DD" />

                        <button type="button" class="btn btn-primary javascript-submit" id="filter-date-submit" onclick="filter_time();">Filter</button>
                    </form>
                </li>
            </ul>
        </div>
    </h1>

JSFiddle

此外，无论出于何种原因，点击表单使其立即消失。这不会发生在我正在使用的实际网页上，仅在JSFiddle页面上。我现在按Tab键绕过了这个问题。

Answer 1

h1 div#date-filter-dropdown ul.dropdown-menu {
    white-space:nowrap;
    min-width: 10px;
}

Answer 2

试试这些：

<ul class="dropdown-menu" id="ddown" role="menu">  //added a id for the dropdown

并添加这些js：

var m = document.getElementById("date-filter-dropdown").offsetWidth;  //get the date div width.
// alert(m);
var n = document.getElementById("ddown");  
n.style.width = m+'px';    // set dropdown width.
