 <Dropdown
            ref={c => {
              this.slideModal2 = c;
            }}
            offsetX={0}
            style={{ width: screenW, height: setSpText(150) }}
            offsetY={this.state.offsetY2}
            cancelable={false}
            value={this.state.value}
            data={this.state.data}
            onChange={this.onChange}
          />
