use select not radio button. whole point of radio buttons single button per input (group) can active @ same time.

radio buttons on mdn

<label>whats breakfast?</label> <select name="select" multiple="true">   <option value="value1">eggs</option>    <option value="value2" selected>bacon</option>   <option value="value3">oatmeal</option> </select>
