title: How to make menu and toolbar in extjs?
body: <p>I'm new in Extjs. I would like to know. Which components I can use, to make a menu and toolbar like in desktop app? 
  I mean something like this.<a href="https://i.stack.imgur.com/IgB5M.gif" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/IgB5M.gif" alt="enter image description here"></a> </p>
  
  <p>I wrote this code, but the result is not similar to desktop app menu.</p>
  
  <pre><code>Ext.define('untitled.view.main.Main', {
  extend: 'Ext.panel.Panel',
  xtype: 'app-main',
  
  width: 200,
  height: 150,
  tbar: [{
      xtype: 'button',
      text: 'Select',
      menu:   Ext.create('Ext.menu.Menu', {
          items: [{
              text: 'JavaScript',
              handler: function () {
                  alert('Selected JavaScript');
              }
          }, {
              text: 'Java',
          }, {
              text: 'C/C++'
          }]
      })
  }]
  </code></pre>
  
  <p>});</p>
