Hello Buddhi,
Thanx for buying Satz theme. As requested here is the code for your header. You can either replace the NavBar chunk in category "mdx_headerConfig" with the following code or create a new chunk and call it in the header position. Name it something like "mdx_LogoSearchMenu".
<div class="site-width">
<div class="row padding20">
<div class="col-md-3 col-sm-3 col-xs-12">
[[$mdx_logo]]
</div>
<div class="col-md-4 col-md-offset-5 col-sm-4 col-xs-12">
<a href="[[~161]]">Login </a> or <a href="[[~162]]"> Register</a>
<div class="clearfix"></div>
[[!SimpleSearchForm? &landing=`54` &tpl=`SimpleSearchTpl`]]
</div>
</div>
</div>
<div class="headerwrap terbg pribdr hidden-sm hidden-xs">
<div class="site-width">
<div class="row">
<div class="header_logo">
<div class="col-md-12 col-sm-12 col-xs-12 menu-bar" >
<nav>
[[Wayfinder?
startId=`0`
&level=`3`
&rowTpl=`First_Level_li_tpl`
&outerTpl=`@CODE: <ul [[+wf.classes]] id="navd">[[+wf.wrapper]]</ul>`
&innerTpl=`Second_ul_tpl`
