$data->addColumn('action', function ($user) {
return '<div class="btn-group" role="group" aria-label="Button group with nested dropdown">
<div class="btn-group" role="group">
<button id="btnGroupDrop1" type="button" class="btn btn-success dropdown-toggle" data-toggle="dropdown" aria-haspopup="true" aria-expanded="false">Action</button>
<div class="dropdown-menu" aria-labelledby="btnGroupDrop1">

<a class="dropdown-item" href="#">Dropdown link</a>
</div>
</div>
</div>';
});
$data->rawColumns(['action']);
return $data->make();
endif;

Answer 1

You are forwarding nothing at all to user query.
Instead of
$users = User::query()->where('status_member', $request->filter);
...
$users = User::query();
try doing
$users = User::where('status_member', $request->filter)->get();
...
$users = User::all();
EDIT:
update your code:
{ data: 'action', orderable: false, searchable: false}
to
{ data: 'action', orderable: false, searchable: true}
