uni-app及各移动端vue.js自定义下拉

isShowSelect: false,
        dataList: [
          {key: -1, value: "POST"},
          {key: 0, value: "GET"},
          {key: 1, value: "DELETE"},
			    {key: 2, value: "PUT"}
        ],
        unitName:'请选择',
这些是写在data里的

	
	
{{unitName}}


	{{item.value}}
	 

css样式，你们自己写吧，给selectBox_list绝对定位就可以了

      arrowDown() {
        this.isShowSelect = !this.isShowSelect;
      },
      select(item, index) {
        this.isShowSelect = false;
        this.unitName = item.value;
      },
这些是写在methods里的
