Grouping

Description

Learn how to group nodes in Foblex Flow, organize nested structures, and use smart geometry features like fIncludePadding, fAutoSizeToFitChildren, and fAutoExpandOnChildHit for dynamic, responsive diagrams in Angular.

Overview

Grouping helps structure complex diagrams by combining related nodes into logical blocks. Groups can be moved as a whole, resized dynamically, and used to manage nested structures. This example demonstrates:

• how to create groups (fGroup) and nest them inside each other;
• how to place nodes inside groups (including node-in-node nesting);
• how to control geometry with:
• fIncludePadding — include inner paddings when calculating bounds,
• fAutoSizeToFitChildren — auto-resize the group to fit its children,
• fAutoExpandOnChildHit — expand the group automatically when children hit the borders.

It also shows how groups can have inputs/outputs like regular nodes, and how connections route accordingly.

When to use

• You want to move several related nodes as a single unit.
• You need to visually separate subsections of a pipeline or editor.
• The group should automatically resize to wrap its content.
• Groups should dynamically expand when children are dragged toward the border.
