Component choices layout

[DarrenSpink]

Hi,

I have the following components for a product:

1 year subscription - £20
2 years subscription - £35
3 years subscription - £50

Each is ticked to be a seperate line item if ticked.

1 year is selected by Default

My question is this....

I want to prevent the ability of selecting more than one tick box, can I do this by turning the three into a dropdown? Or if not / or radio buttons?

Thanks

Use permutations instead, inbuilt help very good on explaining them.
