Answer 1

Since this is a wordpress issue (I believe) you are likely using MySQL to store your data which means you can't use CTEs. What you will have to do is something like this:

In $(document).ready return your result set in JSON write a query something like this:

"SELECT DISTINCT FROM table where AppCategory = 'iPhone 7` LIMIT 0, 50"

This would return 50 records of that category.

Inside the AJAX call you would then populate the select list based on these results.

I will need more info to take you any further.
