Hi Nishith,
Sorry for the late reply.
Your solution works great! Thank you so much for that.
But is there any option to move the menu to top after SELL?
I am working on the module menu pages. I have one issue. I searched about it but could not find any solution.
I am trying to create default bootstrap style admin panel.
When install the module. I set the bootstrap to true. but when i create the menu pages. I see nobootstrap class added to the id content. please check the screenshots.
$this->name = 'inspiration';
$this->tab = 'administration';
$this->version = '1.0.0';
$this->author = 'soundhar';
$this->need_instance = 0;
$this->ps_versions_compliancy = array('min' => '1.7', 'max' => _PS_VERSION_);
$this->bootstrap = true;
parent::__construct();
$this->displayName = $this->l('Gallery Inspiration');
$this->description = $this->l('This module allows create customers own gallery.');
$this->confirmUninstall = $this->l('Are you sure you want to uninstall?');
frames.tpl <div class="row"> <div class="col-lg-12"> <div class="panel"> <h1>test</h1> </div> </div> </div>

so if manually replace nobootstrap to bootstrap it works as i expected. 
is there any solution to remove the nobootstrap class?
Thanks a lot
