how to reduce treeview with checkboxes load time

Hi!

I tested the treeview on a fresh app with about 1300 nodes and unfortunately it's the same thing for me.

I dont think we can do anything about this without changes to the plugin itself. I have added this issue to our list and we will check why it takes so long and if we can do anything to make it faster but I cannot give you an ETA for this.

As of things you can try, maybe some kind of pagination or lazy loading would work there?

Best Regards!

I saw this before. It might be much faster to use array of objects instead of thousand of distinct objects. I'm looking for the next version :)

I optimized Treeview initialization in MDB Pro 9.3.0. The original plugin creates a Collapse instance for every expandable branch. Each constructor searches globally for collapse triggers, repeatedly processing branches that have already been initialized. This becomes expensive on large trees.

The modified plugin: - Temporarily removes data-mdb-collapse-init from a branch trigger after its Collapse instance has registered it. - Excludes Treeview-generated checkboxes without collapse targets from these repeated searches. - Applies the same treatment to triggers in previously initialized Treeview instances, supporting multiple trees on one page. - Restores every attribute and its exact value synchronously in a finally block, including when initialization throws an error.

Collapse controls outside Treeview remain available during initialization. Existing MDB instances, trigger associations and event handlers are preserved. The change is limited to initialization. It preserves the existing selection, accordion, keyboard, filtering and expand/collapse logic.

Optimized MDB Treeview initialization by temporarily excluding already registered branch triggers and targetless checkboxes from repeated global Collapse searches. All attributes are restored synchronously in finally, including on error.

The optimization supports multiple trees and all existing options, while preserving external Collapse controls, event handlers and runtime behavior. Delivered as https://listafirme.ro/platform-static/mdbuipro930/plugins/js/treeview-lf.min.js the original vendor file remains unchanged.

If it helps you, please offer a piece of candy to anyone.
