title: How do I implement Advanced combobox in CakePHP?
body: <p>I have implemented combobox in CakePHP using following statement: </p>
  
  <pre><code>echo $form-&gt;select('brand_id',array($brands),null,array(),'Choose Brand');
  </code></pre>
  
  <p>For brand and input form for category: </p>
  
  <pre><code>echo $form-&gt;input('category_id',array('type'=&gt;'select',$categories,'empty'=&gt;'Choose Category'));
  </code></pre>
  
  <p>But none of above option allows me to add my text input to brand or category, like say I want to add an input which is not there in the combobox, how should I go about it. </p>
  
  <p>Like a link in the combobox or textbox in combobox?</p>
