if her plan is to submit application personally,and she have already the application form filled up, theres no need for her to filled in on line. But if she have filled up already on line,just have a copy of then it, then submit to vfs.I shes going to to ask for a scheduled appointment on line she can filled in the form the managers check,what bank and branch.But if i were your wife,il just call for an appoinment.They will only ask you what bank and number and what branch and when u have paid it.Then they will give the soonest available time immediately..Just let your wife xerox the managers check and include it on the docs to be submitted.
