above is the json i am getting back from the engine

(Optional) Expected behavior the size of the node should be more than 300/300

(Optional) ELK Version snapshot

Does this solve your problem?

ymolists commented 3 months ago

yes indeed it does thank you !

ymolists commented 3 months ago

sorry to bring this but is it possible to

1) restrict the maximum as well ? 2) only do it for one side ? meaning put a minimum/maximum on width only ?

soerendomroes commented 3 months ago

You cannot set a maximum width if you layout bottom-up. If you do it top-down, you can set an exact width and height and the inner content is scaled down.

You could set a very small minimum height to essentially only have a minimum width.
