Connectable Side

Description

Control which side of a connector accepts or emits connections so routing stays cleaner around each node. Use this when a connector should have one active side at a time, with optional automatic calculation for dynamic layouts.

Example

[example.html] <<< https://raw.githubusercontent.com/Foblex/f-flow/main/libs/f-examples/connectors/connectable-side/example.html [example.ts] <<< https://raw.githubusercontent.com/Foblex/f-flow/main/libs/f-examples/connectors/connectable-side/example.ts [example.scss] <<< https://raw.githubusercontent.com/Foblex/f-flow/main/libs/f-examples/connectors/connectable-side/example.scss

Modes in this demo

  • Manual mode for fixed connector sides such as LEFT, RIGHT, TOP, or BOTTOM.
  • Calculated mode with CALCULATE when the best side should depend on relative node positions.

Each connector still has only one active side at a time, so multiple edges will share that side.

Related behavior

If a connection-side rule is also specified, it takes precedence over the connector-side rule. See the Connection Connectable Side example for the stronger per-edge override.
