IIRC, this should be a 1 because that's what's expected by AdminLTE. Also, TRUE is not particularly meaningful in HTML. For example,

> tags$section(`foo`=TRUE)
<section foo="TRUE"></section>

I think this sort of thing should be implemented as an option to sidebarMenu. It's a different HTML structure, but it makes more conceptual sense for users. That's also how disabling the sidebar is done. See:

Hi @wch ,

Thank you for the review. I have now updated code and it works as I would like to see it working (main functionality is there now).
I should note, maybe that I am not a JS guru.

Hello,

I am trying for 3 days without success to implement the "collapsible sidebar which is capable of showing only icons". I don't understant how the links are made between the different R files and those present in the "inst" folder. Is it possible to explain me ? Thank you in advance !

Hello,

Please consider detule@afecd74 for an alternative solution, one that toggles this feature as an option to dashboardSidebar.
