Hi @R K Solanki 

I don't think there is any extensions but it is not just about check-box and 2 input tags, they must have some functionality, first you must want to save it, so you have to either create table to add in order table, if you do so, then also you want to process the data to be picked from frontend and saving to database and in last you want to see in it backend section.

You can break full functionality into small tasks and do step by step.

hope you are clear now what you need to do.

@gaurav_harsh1 yes you are right, but my main question is, I'm very much confused to developing this extension, it was not payment method, but I want to display in the payment section, also its Textbox data should be store in DB and display it to Backend Order,

I have developed this extension as a payment method, but in the real case, it was not a payment method, i have put one Section in Payment Section, that is i don't know how to do that,

please give me some suggestions about this, i hope you have understood my question.
Thanks,
