"... Recreating the sidebar ... other icons ... ?!?"

I doubt anyone understands what this is about. Please put your code on Github. This is a much better chance of following what you had in mind.

Is it possible to display the full top <div> (class row) seen in <div class="container-fluid">?

I can closely recreate the sidebar and right dropdown, but not the other icons.

Brilliant. Thanks

Thank you, Arsalan. Are there other pages not shown under webservices, to do with the other calls related to Evetns, please?

Because it listed here https://www.openteknik.com/webservices/view/35411/events-list you can use API or

$Events = new Events();
$List   = $Events->getEvents(['page_limit' => false]);

I note that Events API is not listed under https://www.opensource-socialnetwork.org/webservices/all

Just seen that the OssnServices and EndPoints software should help. Thank you.
