Is there a way to make a nested if statement using only by structuring nodes out on the GUI vs. writing js in a function node? How would you do it?

Can you provide an example of what you want to do.

You could use swtich nodes nested, a simple example.

I have 2 switches inputting to an XOR node. When a button is pressed I want the state of that XOR to stop/allow the message from the button to proceed.

Not sure what that has to do with nested if. Feed the XOR into a node-red-simple-gate to block or allow the message from the button. Alternatively (possibly better) feed the output of the XOR back to the button, with a change node so as it enables or disables the button.

Oh, maybe I'm wrong. I was looking at it like, IF the button is pressed, IF the XOR is true, etc. I will try the simple gate. Thanks
