我的md-select设置如下:

<md-select placeholder="Category" ng-model="current.Category" flex >

import { BrowserModule } from '@angular/platform-browser';
import { NgModule } from '@angular/core';
import { HttpModule } from '@angular/http';
import { MaterialModule } from '@angular/material'
import { FlexLayoutModule } from '@angular/flex-layout'

    @NgModule({
