Layer7 API Management

I am using API Developer Portal 3.5CR3. If I have 50 or hundreds of API's, then how can I manage all those Apis in the API Developer Portal on the documentation Portal.  As the documentation for the API's will increase and the developers will have a hard time for searching their specific API in the documentation Page.

Did you try using the search bar

Yes, i have tried using the search bar, it works fine. but the client needs a different approach for the list of APIs in the documentation Page.

Hi all, in addition to using our search functionality, you can also take another approach which is to grouping your APIs doc pages under a menu item within the Documentation section. To do so, via staging workspace, create a page under Documentation (e.g. GroupPage). Then, when you publish your API and upload your wadl enter in the "URI for interactive documentation" field the path that includes the menu in it, for example GroupPage/newAPI

I totally agree with you about the grouping of the wadl APIs.  
But according to the customer, their requirement is as follows:-

when we click on the group of the APIs then only the APIs under that group should be seen not the other APIs which are from other group or other APIs.
