更改推送菜单覆盖

请查看更新后的小提琴。我已经将mpp -push的翻译改为导航，id为mpp -menu

    //this._setTransform( 'translate3d(' + translateVal + 'px,0,0)' );
    this._setTransform( 'translate3d(0px,0,0)' ,this.el);

替换此CSS

.mp-pusher {
    position: relative;
    left: 0;
    height: 100%;
  transform: translate3d(0px, 0px, 0px) !important;
}
.mp-pushed .mp-menu{left:300px}

replace

*::before {
    -webkit-box-sizing: border-box;
    -moz-box-sizing: border-box;
    box-sizing: border-box;
