What is the best way to setup a Toggle Button Group with toggle buttons in PluginGuiMagic? I would like the buttons to toggle based on a parameter value that I have setup. I would like to assign an AudioParameterFloat value to each toggle button in the group so that they turn on/off based on the value of 0,1,2 accordingly. I hope this makes sense 
Apologies, this post got lost over the Christmas holidays.
That is a great feature request. So far it is not possible.
It won’t be possible with the RadioButtonGroupId, since for that to work the buttons would need to be siblings, which wont work with the GuiItem wrappers.
I think it could only be added to the “View” containers. I will have a think of it and get back to you.
