Is there any way to target a specific page of the help section to hide the sidebar with css? I ask this, as the template is still the same one across all of the help pages
well it's not the best way to do but it will done it.
are you using html in help page ? if yes
then css can do it
like
<style>
.sidebar-class{
display:none}
</style> abobe the content of help page
