In Web based application:
Category button is some what misplaced after clicking the view all button in the main category.
Please enable sub category wise view to know the various courses.
In Mobile based application:
After clicking view all in the main category,
Search option will disappear from the screen.
Sub category wise view of courses for easy navigation is not found.
I have discussed these requirements with Mr. Vijay, in detail. Please look into this and solve the issue at the earliest. When we have huge number of courses under each category and each sub category, it is very important to ensure user interface is good and serves the purpose.
