I am assuming that the behavior of the component - like, what happens when clicking on a button component - I get to define/code on my end, correct?

You answered:

3c. The components behavior will be defined in toddle, no code needed

However, what if I want to trigger different actions on different external apps using the same component?

Do you mean that the component emits an event that I can listen for on my external app and act accordingly?

Like “click event” for a button, or “change event” on form field (along with the new value)…is that it?
