# FAQ

## Q: How to show popup when node is clicked?

For showing popups, set up a workflow with [Node clicked](/reactflow-for-bubble.io/element-reference/events.md#node-clicked) event, and use the [clicked node ID](/reactflow-for-bubble.io/element-reference/states.md#clicked-node-id) state to reference the selected node's info. See example in the demo.

## Q: Can I load or update the graph later after the page is loaded?

Yes - you can load or update nodes and edges at any time using the [Load nodes and edges](/reactflow-for-bubble.io/element-reference/actions/load-nodes-and-edges.md) action.
