• Custom - Sets the decorator shape as Custom

style

ShapeStyleModel

Defines the appearance of the port

<div id='diagram'></div>

  let port: PointPortModel[] =
[{ id: 'port1', visibility: PortVisibility.Visible, shape: 'Circle', offset: { x: 0, y: 0 } },];
let nodes: NodeModel[] = [{
id: 'node1', width: 100, height: 100, offsetX: 100, offsetY: 100,
}];
nodes.ports = port;
let diagram: Diagram = new Diagram({
...
nodes : nodes,
...
});
diagram.appendTo('#diagram');

verticalAlignment

string

Sets the vertical alignment of the port with respect to its immediate parent(node/connector)

• Stretch - Stretches the diagram element throughout its immediate parent
• Top - Aligns the diagram element at the top of its immediate parent
• Bottom - Aligns the diagram element at the bottom of its immediate parent
• Center - Aligns the diagram element at the center of its immediate parent

visibility

PortVisibility

Defines the type of the port visibility

• Visible - Always shows the port
• Hidden - Always hides the port
• Hover - Shows the port when the mouse hovers over a node
• Connect - Shows the port when a connection end point is dragged over a node

width
