Interactive change Sections

How I can make this:
1. If I select first section all ather section unchecked.
2. If I select second first unchecked and third check.

This only simple example, in real task I want do this with many different sections.

Use the Section.nsh macros. one-section.nsi is an example of sections working like option buttons.

Thanks, but I have this structure:

1. SubSection

  a. Section

  b. Section

2. SubSection

  a. Section

  b. Section

And I want that only 1 section must be checked.
I write

Function .onSelChange

	!insertmacro StartRadioButtons $1

	  !insertmacro RadioButton ${Section1}

	  !insertmacro RadioButton ${Section2}

	  !insertmacro RadioButton ${Section3}

	  !insertmacro RadioButton ${Section4}

	!insertmacro EndRadioButtons

FunctionEnd

but if I click on not active subsection 2 sections checked.
