Question

如果我选中一个复选框，则下拉列表应仅显示在该列表的旁边，而是显示在其下的所有其他列表中。

这是我用html代码

的css

＆＃13;

.sub-nav { display: none; }

input[type=checkbox]:checked + label ~ .sub-nav { display: inline; }

＆＃13;

<html>
<body>
<input type="checkbox" name="lingue" value="ing" id="ing"><label for="ing">Inglese</label>&emsp;
                <select class="sub-nav">

你应该使用直接相邻的兄弟选择器（+）而不是一般的兄弟选择器（~）

＆＃13;

.sub-nav { display: none; }

input[type=checkbox]:checked + label + .sub-nav { display: inline; }

＆＃13;

<html>
<body>
<input type="checkbox" name="lingue" value="ing" id="ing"><label for="ing">Inglese</label>&emsp;
                <select class="sub-nav">
                    <option value="ott">Ottimo</option>
                    <option value="buo">Buono</option>
                    <option value="suff">Sufficente</option>
                    <option value="scol">Scolastico</option>
                    <option value="pess">Pessimo</option>
                </select>
            <br>
