Make checkboxes select-able one at a time like radio-buttons
<p>I am looking for some help making checkboxes behave like radio-buttons in that one in a group can only be selected at a time with jQuery.</p>

<p>First, why not use radio-buttons ? Because I want these forms of input to also be un-select-able / un-check-able so that the potential exists that none of them can be checked.</p>

<p>So I have 9 input type checkbox that are grouped in 3 groups of 3, not in forms, just grouped by the fact that those 3 have the same value to the name attribute.</p>

<p>All 9 checkboxes have the class of .secondary-input but only 3 have the name of one, then the next 3 a name of two, and the last three a name of three.</p>

<p>What I am trying to accomplish is that only one of the group is checked at a time and that one can be unchecked so that none in the group are checked.</p>

<p>I would greatly appreciate all and any help in achieving this.</p>

<p>I found a JSFiddle like this, but the jQuery didn't work with my system of groups by the name attribute.</p>
