To show articles based on Filter in 'All categories'
As of now, there is no way to just filter out and see the articles just based on a specific category. As a result, always all articles across categories are visible throughout homescreen or sub-screens. With large number of articles it becomes really cumbersome to navigate.
Idea is to show only those articles across based on category selection. E.g. If i select 'Customer Service', then all articles under customer service folder should only remain. If I need to go back and see all, I can select 'Show All' or 'All categories'.
