title: Select default value in dropdown using SAPUI5
body: <p>I am facing issue while setting the default value in dropdown box in SAPUI5.</p>
  
  <p>Currently I am using below code : </p>
  
  <pre><code>fields : [ new sap.ui.commons.DropdownBox("Cities", {
      selectedKey: "City3",
      items : [ new sap.ui.core.ListItem("City1", {
        text : "DE (Germany)"
      }), new sap.ui.core.ListItem("City2", {
        text : "GB (United Kingdom)"
      }), new sap.ui.core.ListItem("City3", {
        text : "IN (India)"
      }), new sap.ui.core.ListItem("City4", {
        text : "US (United States)"
      }) ]
    })
    }) ]
  </code></pre>
  
  <p>But In List box always it shows <code>DE (Germany)</code> value but I want to default set other value. </p>
  
  <p>How to do that?</p>
