Is this possible on Konva.js?

Question

JavaScript

there is such a task: there are 3 canvas
rectangles, drag works in the highlighted green color (you can drag with the mouse from anywhere in the block and change the size of the rectangle ) ? if yes, I will dig further, if not, tell me so that I don’t waste my time

Answer 1

you mean that there was a connection between objects? pulling down the central one decreases the one below it?
In general, programming teaches that everything is possible, but this does not mean that all tasks must be solved programmatically.
