根据选择的单选按钮有条件地隐藏 nsis 安装程序中的部分

Question

How can a section be hidden conditionally on check or uncheck of RadioButtons in MUI NSIS installer Components Page dialog.

I have added 2 RadioButtons, DEMO & BACKUP.

When user chooses, DEMO RadioButton, then Section displayed will be "INSTALL DATA OR NOT", it can be checked or unchecked by the user, & "BACKUP DATA OR NOT" section would be hidden.

When user chooses, BACKUP RadioButton, then Section displayed will be "BACKUP DATA OR NOT", it can be checked or unchecked by the user, & "INSTALL DATA OR NOT" section would be hidden.

IF I USE THE - SIGN, then the section "INSTALL DATA OR NOT" is hidden for BOTH RADIOBUTTON CHOICES, ie for DEMO also & for UPDATE also, please help.

Also, there are features of SelectSection or UnSelectSection, but they do not hide the Section, which is what I want, that the Section should be hidden and unchecked.

A hidden section has no name so you need to give it a name for it to become visible again:

!include Logiclib.nsh
!include Sections.nsh

page Components InitComponentsPage

!define INSTALLSECTIONNAME "Install"
section "" SEC_INSTALL
sectionend

!define BACKUPSECTIONNAME "Backup"
section "" SEC_BACKUP
sectionend

Function InitComponentsPage
${If} $InstallType == BACKUP
    SectionSetText ${SEC_BACKUP} "${BACKUPSECTIONNAME}"
    !insertmacro UnSelectSection ${SEC_INSTALL}
    SectionSetText ${SEC_INSTALL} ""
${Else}
    SectionSetText ${SEC_INSTALL} "${INSTALLSECTIONNAME}"
    !insertmacro UnSelectSection ${SEC_BACKUP}
    SectionSetText ${SEC_BACKUP} ""
${EndIf}
Functionend
