Can horizontal and vertical switching display be added?

Yes it is possible. But I need time to test some things.

OK. I found a problem. That is, when I quickly collapse and expand, the double-click magnification effect will be triggered. But I just want to collapse and expand!

I see, I'll look into it

I tried to make some changes, but the connecting line is always calculated incorrectly.

It can be done with some css changes if the elements allow it.

But I want to change the behavior of the lines and get rid of the nested structure. If I can do that, the performance will improve.

In order to do that I need to set/get all nodes positions correctly and add/draw lines between nodes with svg.

Wow! Your idea suddenly enlightened me.

If adjusted with CSS, how can it be implemented? Can you provide me with some ideas? Thank you.
