In the process of implementing an registration page that will be seen by two types of users (those registering to buy from the site, and those registering to sell on the site). The current functionality is one button that displays information for both types of users, we are splitting this into two buttons:
The spec for this change was to show both sets of reasons to register, but re-order them so that the information relevant to the button clicked would go to the top. Having implemented it it looks quite cluttered and confusing.
I feel that it would be better to only show the information relevant to the button that was clicked. To me at least it make sense to show a user information they have asked for and no other.
Are there rules of thumb for hiding information when users have made a positive action?
