In Community Site, I have created SP Groups for each Category of the Categories List. I let the SP Group Owner to add users to the respective SP Groups. These users are considered as Experts of the respective Category.
To link the Category to the correct SP Group: I added a column (named Experts) to the Categories List and entered SP Group URL for each of the categories. Example:http://webapplication/_layouts/15/people.aspx?MembershipGroupId=30
Now Experts (of each category) are replying to Discussion topics. Those replies (of each category) from those Experts need to be highlighted using CSS to let the user know that these Replies are from an Expert.
How could I achieve this using client side coding?
