title: Cakephp background color for multiple input
body: <p>I have an input form in my Cakephp 2.x application as below:</p>
  
  <pre><code>echo $this-&gt;Form-&gt;input('color_id', array('label' =&gt; 'Color', 'options' =&gt; $colors, 'empty' =&gt; false, 'multiple' =&gt; true));
  </code></pre>
  
  <p>I want to add css to the input where the background of the select is differ based on the option.</p>
  
  <p>if color is red, the background color is red.</p>
  
  <p>I already try this way:</p>
  
  <pre><code>echo $this-&gt;Form-&gt;input('color_id', array('label' =&gt; 'Color', 'options' =&gt; $colors, 'empty' =&gt; false, 'multiple' =&gt; true, 'style' =&gt; 'background:yellow;'));
  </code></pre>
  
  <p>but its for the whole input[type=select], not for each option.
  can anyone help me? Thanks in advance.</p>
