Ok first things first. I did not design this layout but all feedback is appreciated. I have a web app that takes in a user file and spits out a table. the table also has hierarchy.
Lets say its a sales analysis tool and you upload the companies you sold to. This tree is an industry report that tells the user his performance in specific industries. Now the industries are nested. Example - Computer Hardware -> Memory Device manufacturing -> Solid state memory device industry.
there could be many levels depending on the industry and the user's imported sales file.
Problem is, there may be thousands of industries within a particular 'Parent item'. So if I paginate on lets say 100 items per page, I would violate that if I expand the first parent item. and I cannot calculate how many total level 4 items there are and fix pagination on that because that is causing page load delays.
I absolutely need the tree table because the other columns have numbers that users can compare on.
not having pagination at all will be very messy and long.
There are filters that you can use and cut down the # of parent items based on any of the variables in the other columns.
