title: DropDown List issue in yii
body: <p>help me out with this issue.
  Am using yii.</p>
  
  <p>I have a column called imei in my table -> Mob</p>
  
  <p>Now in my view I have created 3 activedropdown lists based on same field imei on same table -> Mob.</p>
  
  <p>but values are different, i.e I have grouped some ten values in each drop down list.</p>
  
  <p>So user can select any option from any dropdown list and it will be processed. </p>
  
  <p>Problem is when I click button for post action it is taking only last drop downlist value and if last list value is not selected then it is passing null value.</p>
  
  <p>Ex: My 'A' dropdownlist contains 1,2,3
  My 'B'  dropdownlist contain 4,5,6</p>
  
  <p>When I do post action and access through model->imei am getting only 'B' drop down list values.</p>
  
  <p>What I need is to get the value of selected option irrespective of order. if 'A' list value is selected then 'A'.</p>
  
  <p>if both are selected then 'B'. priority from lower to higher. </p>
  
  <p>Can you gives help me out how to acheive this?</p>
  
  <p>Hope Am clear to you ppl or is it wrong approach? tell me the better approach. </p>
