How to get collapsed nodes in cytoscape.js

Question

I have some nodes which are grouped and collapsed. when I get nodes with cy.nodes(), I only get expanded nodes.

how to I can get all nodes that aren't expanded and not rendered in the current view?

Answer 1

I did it by using api.getCollapsedChildren(node) as written in cytoscape.js-expand-collapse document.

let children = collapseApi.getCollapsedChildren(node);
if (children && children.length > 0) {
   children.each((child) => {
       let nodeId = child.id();
   });
}
