You can bind the State property of the radio button to the Visible property of the Label or DropDown widgets.For example, if you select the Staff radio button, the State property of that widget will be set to true, and you can bind that to another widget to make it visible by binding it to the Visible property of that widget.
There is no state property in generic radio button, please refer the below attachment
Refer to the link below, which i have answered earlier, i think it will work for you.
The information provided by @abhiramk is accurate. You can bind the SelectedText property of the Generic Radio Button widget to an Expression widget, which you can program to verify the text and return true or false as output, and bind to the Visible property of desired widgets.
You could tie the selected text parameter to an expression widget that has a boolean output
