I Let's say I have a ussd application to provide the following contrived services from this Menu: 1 - get free joke 2 - register for paid joke (ie 10 jokes/day) 3 - get balance for paid joke (remaining )
Under 1 I have other options like categories : 1 - satire 2 - nerdy 3 - explicit
Under 2 I could have options like: 1 - tumblr 2 - yahoo 3 - hotmail
Under 2-1 for example it can show payment options like : 1 - paypal 2 - stipe
Then under 2-1-1 , it can ask for email, then password or so etc. This can get other nested structure where some payment method are enabled for some vendors or not etc. |
