We have an exsiting website which implented with one Joomla extension,
which could let users buy course and have course online.
(1) Build a page that could filter the courses by categories.
And we need somebody to help us that,
build a category layout, based on the functions of this course extension.
( The course extension itself has categories & sub-categories while we create the courses)
We neeed you to create menu at frontend that could connect with these values in backend.
Example : [login to view URL]
(2) Create a search bar as a module.
We need this search bar module could insert in the website menu.
The search bar need to search for the courses which relate to the keywords input.
example : [login to view URL]
There's a search bar in menu.
I had drawn a logic map that might help.
