Toggle button to "Down" when changing application state?

Question

I am trying to make a button component modal so that when I click it, the application changes to a different state and the button stays in the button "down" state. Then if I click a different button, the application state changes again, the first button changes to the "up" state and the second button changes to the "down" state. Basically, I want radio button actions, but on a styled button.
Is there a way to do this in Catalyst or do I have to handle this in the FB code?

Answer 1

I had some difficulty getting Catalyst to allow me to set the states of toggle buttons added to my project. So, I decided to create my own custom toggle button to give me the ability to fully style it. Here's the process I followed:
converted my styled "normal" buttons back to artwork
Converted the artwork to a custom component
Created states for custom component for Unselected, Selected, Over, etc.
Associated the artwork from Illustrator to the appropriate states for the custom component
set the custom component state (e.g., unselected, selected...) for the each of the appropriate application states
set the component action to "transition to state" when the custom component is "clicked"
Renamed the custom component in the library to "CustomToggleButton"
Exported the CustomToggleButton library component and then imported it so it was reusable in my library
