title: In ExtJs 3.3.1, how can I show a ComboBox drop down without click in EditorGrid?
body: <p>I am using ExtJs 3.3.1.</p>
  
  <p>Within an EditorGrid, my "editable" column has a ComboBox as its editor. How can I have the ComboBox always showing for each row? Meaning, the user would not have to click on a cell to know there is a ComboBox there.  Currently, I have clicksToEdit set to 1, but I wish I could set this to 0 (I tried that).</p>
  
  <p>See some of my code below to see my current configuration.</p>
  
  <pre><code>var combo = new Ext.form.ComboBox({
      typeAhead: true,
      triggerAction: 'all',
      lazyRender: true,
      mode: 'local',
      store: new Ext.data.ArrayStore({
          id: 0,
          fields: [
              'statusId',
              'displayText'],
          data: data
      }),
      valueField: 'statusId',
      displayField: 'displayText'
  });
  
  var cm = new Ext.grid.ColumnModel({
      columns: [{
          id: 'orderId',
          header: 'ID',
          dataIndex: 'id',
          width: 50
      }, {
          header: 'Status',
          dataIndex: 'status',
          width: 130,
          editor: (data.length == 1) ? null : combo,
          renderer: Ext.util.Format.comboRenderer(combo)
      }, {
          id: 'orderSummary',
          header: 'Summary',
          dataIndex: 'summary',
          renderer: this.renderSummary
      }]
  });
  
  var orderGrid = new Ext.grid.EditorGridPanel({
      store: this.getOrderStore(),
      cm: cm,
      autoExpandColumn: 'orderSummary',
      clicksToEdit: 1
  });
  </code></pre>
