This is the sample link from here also.
I've just wanted to know what is the best approach to render it fast.
On the link I provided you will see a tree view coming out from database.
What should I do to render it fast. Here's what I think please guide for better approache(s).
1) Load only parent, then load children when the parent was clicked. (What I think was, why should I fetch all data if I am not using it. That's why I only load parent then the children when the parent is clicked. Is right or not).
2) Build the tree view in api/controller before sending it back to frontview so when the loading was complete all data was already built. (but it takes to fetch coming out from api, the user will see broken menu tree view. Lets say I have e-commerce site like this. below image). How to build menu like this in fastest way without seeing broken tree. (The image is sample to see expected result.)
Happy Coding!
