View source for Graying out Section (define mandatory sections)

{{PageAuthor|ssp}}

== Description ==
When creating my first installer recently I wondered if it was possible to define section '''mandatory''', so that the user can not unselect them (e.g. needed components as shared libraries).

So I stumbled across SectionSetFlags



== Procedure ==
Just add 
<highlight-nsis>
    SectionSetFlags ${SEC0000} 17 
</highlight-nsis>
to 
<highlight-nsis>
Function .onInit.
</highlight-nsis>
17 by the way means SF_SELECTED & SF_RO, what tells windows select the checkbox before Section SEC0000 and make it read-only. To get to know all possible SF_ flags, look at the given reference.
