[Question] How to disable automatic wrapping? #310

Closed mscandan closed 1 week ago

mscandan commented 1 week ago

Ask your questions Hello, I am using ElkJS with ReactFlow.

I am using partitions to separate some nodes to a specific partition. When I add more nodes to a column, after some number of nodes it gets wrapped and creates a new column in the partition. I'd like to achieve only one column view. Do you have any tips on achieving this view?

I've created this example

(Optional) Expected behavior I want every node in every partition to be in top to bottom order.

(Optional) Screenshots Current State:

Desired View:

View with setting elk.hierarchyHandling to INCLUDE_CHILDREN

(Optional) ELK Version The ELK or elkjs version: v0.9.3

The problem is that you are using layered for a graph with no edges so the nodes are layouted as separate components. One way you can achieve your goal is by using rectpacking and setting the aspect ratio to a suitable value (see example).

Alternatively you could use layered, add edges, and make them invisible in the rendering.

The aspectRatio option appears to also work for layered so you don't need to use rectpacking.

@Eddykasp thank you so much, my problem resolved with the aspectRatio
