title: Theming and layout in yii framework
body: <p>I am a newbie in Yii Framework and creating a CRM which is module based.
  Using different tutorials I am able to create my own theme, but now I am stucked at one point.</p>
  
  <p>In my theme, the upper <code>&lt;nav&gt;</code> and left <code>&lt;nav&gt;</code> remains the <em>same</em> throughout the app, until user is logged in. That's why I made it a part of my <strong>main.php</strong>, but in the login page there are no buttons to show, just simple <em>login form</em> with 2 <em>textfields</em>.</p>
  
  <p>How can I implement this form in my application using custom themes?</p>
  
  <p>I have tried to define a layout in that particular action but not succeeded. Any help would be appreciated.</p>
