How To Make It No Delivery Method Is Selected By Default

we use cscart 3.0.4 and did some customization.

when user purchase products and go to checkout page, the first delivery method is selected by default currently.

But I want no delivery method is selected by default. How to make it?

I find what I selected is remembered until submitted the order. This is good feature.

Just want no method is selected when user go to checkout page at the first time. Then user have to select one purposely. otherwise user may be missed it, but use the default selection wrongly.

Thank you.

It is a radio group and if you didn't display it as selected, it will post with the first value anyway.

You could create a “please select preferred shipping” method that had a price of your choosing.
