To create the module position add the following to your templates index.php (../templates/j51_oxygen/index.php) just after
<div id="header"> (line91)..
<div id="topsearch">
<jdoc:include type="modules" name="topsearch" />
</div>
You must then style it with the following which you can add to the end of your templates template.css (../templates/j51_oxygen/css/template.css)
#header {
position: relative;
}
#topsearch {
position: absolute;
height:50px;
width:300px;
top:25px;
left:660px;
margin:0;
padding:0;
z-index:99999;
}
#header .search .inputbox {
background:#fff !important;
}
And that should be it. You'll find the position won't be listed in the positions dropdown so simply type it in to create (
topsearch).
