How to deselect radio button when another radio button is selected?
<p>I was wondering if there is a way where i have i 2 groups of radio button
eg </p>

<p>group 1</p>

<pre><code>&lt;input  type="radio" name="things" value="car" /&gt;  car
&lt;input  type="radio" name="things" value="car" /&gt;pen
&lt;input  type="radio" name="things" value="car" /&gt;TV
</code></pre>

<p>group2</p>

<pre><code>&lt;input  type="radio" name="things" value="exam" /&gt;  exam 
&lt;input  type="radio" name="things" value="journey" /&gt;journey
</code></pre>

<p>the question is if i select radio button from group2 
Eg exam it should deactivate radio butons car And Tv from group1 and allow only pen radio button active</p>
