Hey Marvin,

You can edit the file /plugins/payplans/offlinepay/offlinepay/app/offlinepay/transaction.xml and remove the following options,

[gist]
<option value="Cheque" params="id,amount,currency">COM_PAYPLANS_Cheque</option>
<option value="DD" params="id,amount,currency">COM_PAYPLANS_Demand_Draft</option>
[/gist]

no, it then displayes checkque in the second line as default.
Can we somehow had just one input field instead of select options. It can be readonly or smthg?

Hey Marvin,

I am not too sure if I understand your requirements here. Do you mean that you only want to show "Cash", in the offline payment method, http://take.ms/zbHHZ ?

I have tested the modifications on my end and I only see the cash method as you can see here, http://take.ms/Us9rX

yes, but you see, though only cache is an option, input box for DD/Cheque number is displayed below.
That wont make sense.

A quick work around that you could apply is to add the css codes below:

[gist]
body .control-group.gateway_paramsid {
display: none;
}
