使用Chrome Dev Tools切换设备工具栏打开时，Stellarnav插件无响应

Question

我使用的是Stellarnav移动友好型Dropdown插件，当浏览器窗格的宽度减小到断点设置以下时，响应部分起作用。当通过使用Toggle-Developer工具在chrome开发人员工具上启用了不同的移动设备时，相同的响应似乎不起作用。

  jQuery('#main-nav').stellarNav({

 // adds default color to nav. (light, dark)
  theme     : 'plain', 

 // number in pixels to determine when the nav should turn mobile friendly
  breakpoint: 960, 

 // label for the mobile nav

 // adds a click-to-call phone link to the top of menu - i.e.: 
 "18009084500"
 phoneBtn: false, 

 // adds a location link to the top of menu - i.e.: "/location/", 
 "http://example.com/"
  locationBtn: false, 

 // makes nav sticky on scroll
  sticky     : false, 

 // how fast the dropdown should open in milliseconds
  openingSpeed: 250, 

 // controls how long the dropdowns stay open for in milliseconds
 closingDelay: 250, 

 // 'static', 'top', 'left', 'right'
  position: 'static', 

  // shows dropdown arrows next to the items that have sub menus
  showArrows: true, 

  // adds a close button to the end of nav
  closeBtn     : false, 

 // fixes horizontal scrollbar issue on very long navs
 scrollbarFix: false,

  // enables mobile mode
  mobileMode: false

});
