在悬停时显示php / mysql中的控件

Question

I have below radio button on my web,

<input id='element_1_1' name='element_1' class='element radio' type='radio' value='1' />
<label class='choice' for='element_1_1'>2!</label>
<input id='element_1_2' name='element_1' class='element radio' type='radio' value='2' />
<label class='choice' for='element_1_2'> 1 </label>

When user is between the option, I want a check box to appear or a radio button using which user can select 1.5, the radio button should not appear usually only on hover, any ideas how to do it. I am guessing javascript is involved but all results on SO have jQuery in them which I have no idea about
