html - 如何设置 Materialize 选择元素的大小？

Question

关于 Materialize 选择元素，我希望可见的选项数量为 5，但事实并非如此。我也尝试设置高度，但也没有运气。

                                <div class="input-field col s4">
                                    <select id="add_cusine_type" size="5">
                                        <option value="" disabled selected>Choose your cuisine type</option>
                                        <option value="Australian">Australian</option>
                                        <option value="American">American</option>

Answer 1

Materialize为选择选项使用下拉菜单（它实际上是由文本输入触发的下拉菜单）。所以你需要定位下拉类：

.select-dropdown {
  height: 300px;
}

您可以简单地在包装 div 中指定它，我的示例是 300px

<div class="input-field col s4" style="width:300px">
   <select id="add_cusine_type" size="5">
      <option value="" disabled selected>Choose your cuisine type</option>
      <option value="Australian">Australian</option>
      <option value="American">American</option>
      <option value="British">British</option>
      <option value="Carribean">Carribean</option>
      <option value="Chinese">Chinese</option>
      <option value="French">French</option>
      <option value="Greek">Greek</option>
      <option value="Indian">Indian</option>
      <option value="Italian">Italian</option>
      <option value="Japanese">Japanese</option>
      <option value="Mediterranean">Mediterranean</option>
      <option value="Mexican">Mexican</option>
      <option value="Moroccan">Moroccan</option>
