How to change shapes in canvas

[awsomedesigner]

I want to change all shapes on the canvas and want to add my custom element. also, I want to show sidebar form when an element is placed on the canvas.

Also if the parent element is connected to the child node then the child element will not be connected to the parent element, how can I set this type of condition on this editor.

Also, need one more thing, right now there are only 4 connections, I want to add more than 10 connection in a single element. how can I set multiple connections?

` const { executeCommand, update } = this.$refs.xxx.propsAPI; executeCommand(() => { update(item, { shape: 'xxx' } }) });
