egui_ltreeview is a tree view widget for egui

This tree view widget implements all the common features of a tree view to get you up and running as fast as possible.

Features:

• Directory and leaf nodes
• Node selection
• Select multiple nodes
• Keyboard navigation using arrow keys
• Frontend for Drag and Drop support
• Agnostic to the implementation of your data.

Getting started

let id = ui.make_persistent_id("Names tree view");
TreeView::new(id).show(ui, |builder| {
    builder.dir(0, "Root");
    builder.leaf(1, "Ava");
    builder.leaf(2, "Benjamin");
    builder.leaf(3, "Charlotte");
    builder.close_dir();
});

Create a new TreeView with its unique id and show it for the current ui. Use the builder in the callback to add directories and leaves to the tree. The nodes of the tree must have a unqiue id which implements the NodeId trait.
