CSS（LESS）

.select {
  display: flex;
  flex-direction: column;
  border: 0.01rem solid #666;
  height: .4rem;
  &:focus-within{
    border: 0.01rem solid #409eff;
  }
  >div {
    height: .4rem;
    flex-shrink: 0;
    padding: 0 .4rem 0 .1rem;
    display: flex;
    justify-content: space-between;
    align-items: center;
    position: relative;
    outline: none;
    font-size: .14rem;
    border-radius: .03rem;
    min-width: .8rem;
    &::after {
      content: '';
      border: 0.08rem solid #666;
      border-bottom-color: transparent;
      border-left-color: transparent;
      border-right-color: transparent;
      position: absolute;
      right: .1rem;
      top: calc(50% - .03rem);
    }
    &:focus{
      border-color: #409eff;
      &::after{
        content: '';
        border: 0.08rem solid #409eff;
        border-top-color: transparent;
        border-left-color: transparent;
        border-right-color: transparent;
        position: absolute;
        right: .1rem;
        top: calc(50% - .12rem);
      }
      & + ul {
        display: block;
      }
    }
  }

  >ul {
    display: none;
    margin-top:.1rem;
    background-color: #fff;
    border: 0.01rem solid #666;
    width: 100%;
    cursor: pointer;
    border-radius: .03rem;
    z-index: 9;
    &:hover{
      border: 0.01rem solid #409eff;
    }
    >li{
      height: .3rem;
      font-size: .14rem;
      padding: 0 .1rem;
      display: flex;
      align-items: center;
      &:hover{
        background-color: #409eff;
        color: #fff;
      }
    }
  }
}

使用方式:

 <d-select  v-model="value" :options="options"/>

data(){
	return {
		value: '',
		options: [
			‘click’,'change','input','load','touchstart','touchmove','touchend'
		]
	}

}
