x-flow-collapse

Toggle collapse and expand for node hierarchies. When a node is collapsed, its children are hidden and edges to them are tucked away.

<div x-data="flowCanvas({
    nodes: [
        { id: 'group', type: 'group', position: { x: 20, y: 10 }, data: { label: 'Team' }, dimensions: { width: 260, height: 150 } },

Props

Prop	Type	Default	Description
`instant`	`bool`	`false`	Skip animation, collapse/expand immediately
`all`	`bool`	`false`	Collapse or expand all collapsible nodes at once
`expand`	`bool`	`false`	Expand only (no toggle)
`children`	`bool`	`false`	Collapse children of a node

Usage

Inside a node template

When placed inside a node template, the button auto-binds to the current node.id:

<x-slot:node>
    <span x-text="node.data.label"></span>
    <x-flow-collapse>Toggle</x-flow-collapse>
</x-slot:node>

Instant (no animation)

<x-flow-collapse :instant="true">Toggle</x-flow-collapse>

Batch operations

Collapse or expand all nodes from outside the node template:

<x-flow-collapse :all="true">Collapse All</x-flow-collapse>
<x-flow-collapse :all="true" :expand="true">Expand All</x-flow-collapse>

Collapse children only

<x-flow-collapse :children="true">Collapse Children</x-flow-collapse>

Directive mapping

Maps to: x-flow-collapse with modifiers (.instant, .all, .expand, .children)
