如何对齐 bootstrap-vue 下拉按钮项目

Question

如何水平对齐下拉按钮子项目。我无法通过 CSS 对其进行自定义。控制 link 是 here

预期设计：

    new Vue({
  el: '#app',
 
data:{
       
         fruits: ['Apple', 'Banana', 'Orange'],
         selectedFruit: '',
       
     },
     methods: {
    selectFruit (index) {
      this.selectedFruit = this.fruits[index]
        }
      }
})

   

 .dropdown-demo {
  width: 200px;
  background-color: white;
  border-bottom: solid 1px black;
  >div {
    background-color: azure;
    width: 100%;
    button {
      background-color: yellow !important;
      padding-left: 0;
      padding-right: 0;
      width: 100%;
      text-align: right
    }
  }

                         @click="selectFruit(id)"
                         :key="id">
                {{item}}
              </b-dd-item>
            </b-dropdown>
          </div>
</div>

Answer 1

向包含 slot="button-content" 的 div 添加一个名为 dd 的 class，它具有以下规则：

  .dd{
    width:190px;
    display:flex;
    flex-direction:row;
    justify-content:space-between;
    align-items:center;
    }

new Vue({
  el: '#app',
 
data:{
       
         fruits: ['Apple', 'Banana', 'Orange'],
         selectedFruit: '',
       
     },
     methods: {
    selectFruit (index) {
      this.selectedFruit = this.fruits[index]
        }
      }
})

.dropdown-demo {
  width: 200px;
  background-color: white;
  border-bottom: solid 1px black;
}

.dd{

width:190px;
display:flex;
flex-direction:row;
justify-content:space-between;
align-items:center;
}
