Because you’ve different value for name
attribute, they should have a common name
value, just like you group items.. for example
<input type="radio" name="group1" />
<input type="radio" name="group1" />
<input type="radio" name="group1" />
<!-- You can select any one from each group -->
<input type="radio" name="group2" />
<input type="radio" name="group2" />
<input type="radio" name="group2" />
