Question

我正在尝试使用css将选择下拉列表显示为弹出菜单。我正在尝试显示此链接中的选择菜单。

我尝试了一些样式，但它显示为正常的下拉列表。

无论如何都要将选择菜单显示为弹出式dropdown

Answer 1

一种方法是使用href和<h2 id="caption"></h2> <canvas id="img_1" width="500" height="400"> <--!input type="submit" onclick="canvas(); return false;"!--> </canvas><br><br> <input type="submit" id="prevpic" value="Previous" onclick="previmg()"> <input type="submit" id="nextpic" value="Next" onclick="nextimg()">选项。对于纯css弹出窗口来说，这是一个聪明的伎俩（见here）。但是，这意味着您必须将列表放在链接中，这会导致几个css问题。这是我的尝试，绝对需要一些风格修复...

:target

$('#target2').on('change', function() {
  $('#target1').val(this.value);
})
