如何根据第二列的内容调整下拉列表中每一行的高度？

问题描述 投票：0回答：3

我使用selectMenu jQuery小部件创建了一个下拉列表，然后在Angular中使用它创建了一个下拉组件，这样我就可以重用相同的组件。现在，我面临的问题是下拉列表由3列组成，第2列包含每行的主要内容。现在，每当我增加要放入第二列的内容的大小（长度）时，每行的其他两列的高度不会动态调整。我对如何解决这个问题很困惑？下面给出了我创建的下拉列表的图像，其中行的未调整高度。

enter image description here

这是codepen页面的链接，其中包含示例和我使用过的代码：Codepen Dropdown link。我试图通过在CSS文件中使用display:table-cell;来解决这个问题，但我的努力是徒劳的。请建议如何解决此问题。此外。这是我想要的输出。 enter image description here

下面给出的是代码片段。

$(function() {
  $.widget("custom.mySelectMenu", $.ui.selectmenu, {
    _renderMenu: function(ul, items) {
      var that = this,
        currentCategory = "";
      $.each(items, function(index, item) {
        var li, name, short, price;
        if (item.optgroup != currentCategory) {
          ul.append(
            "<li class='ui-selectmenu-category'>" +
            item.optgroup +
            "</li>"
          );
          currentCategory = item.optgroup;
        }
        li = that._renderItemData(ul, item);
        console.log(ul);
        name = li.text();
        short = item.element.data("short");
        price = item.element.data("price");
        console.log(li, short, price);
        li.prepend(
          $("<span>", {
            class: "short"

        );

        li.append(

你可以使用display:table和display:table-cell

$(function() {
  $.widget("custom.mySelectMenu", $.ui.selectmenu, {
    _renderMenu: function(ul, items) {
      var that = this,
        currentCategory = "";
      $.each(items, function(index, item) {
        var li, name, short, price;
        if (item.optgroup != currentCategory) {
          ul.append(
            "<li class='ui-selectmenu-category'>" +
              item.optgroup +
              "</li>"
          );
          currentCategory = item.optgroup;
        }
        li = that._renderItemData(ul, item);
        console.log(ul);
        name = li.text();
        short = item.element.data("short");
        price = item.element.data("price");
        console.log(li, short, price);
        li.prepend(
          $("<span>", {
            class: "short"
          }).html(short)
        );

        li.append(
          $("<span>", {
            class: "price"
          }).html(price)
        );
        if (item.optgroup) {
          li.attr("aria-label", item.optgroup + " : " + item.label);
        }
      });
    }
  });

  $("#options").mySelectMenu({
    width: 300
  });
  $("#options")
    .mySelectMenu("menuWidget")
    .addClass("overflow");
});
.ui-menu .ui-menu-item {

  float:right;
  padding-right: 40px;
}

.ui-menu-item .ui-menu-item-wrapper {
  display: table-cell;
  vertical-align:top
  padding: 1em 2px;
}

Very simple fix, add this:

.ui-menu .ui-menu-item:not(.ui-selectmenu-category) {
  display: flex;
}

根据你的代码添加这个display: flex;

.ui-menu .ui-menu-item {
display: flex;
height: auto;
flex-direction: row;
margin: 0;
cursor: pointer;
list-style-image: 
}
