SB Admin 2 Sidebar menu expands on load

Question

I'm trying out SB Admin 2 template with laravel 5. It works fine. Except for sidebar menu which expands and collapses second and third level on every load. I'm not sure if its ok to link the demo here, but it can be seen in their demo

Has anyone been bothered by this before and perhaps found the solution? I would like the menu to load collapsed. Right now it looks buggy on every reload.

Edit: I added the markup if it helps Markup

            <div class="navbar-default sidebar" role="navigation">
            <div class="sidebar-nav nav-collapse">
                <ul class="nav" id="side-menu">
                    <li class="sidebar-search">
                        <div class="input-group custom-search-form">
                            <input type="text" class="form-control" placeholder="Quick search...">

Answer 1

I've encountered this problem before, make sure there is no inline CSS inside lists <li> of the sidebar. or if you have the class "active" per default. deleting these will solve your problem. Otherwise in every collapsable <ul> (the ul's with class nav.nav-level) add this class collapse Example: <ul class="nav nav-second-level collapse">

Answer 2

in last version of SB Admin 2 you must add class inside and of navbar like that:中添加 class 和导航栏的 ，如下所示：

in body add class : 
in ul add class : 

Must be like that:
