Hello,
Thanks for your Valuable Patience!
Consider checking this Example: http://themes.semicolonweb.com/html/canvas/login-register.html . Would this be something you could consider using? You can definitely add your own Custom Content in the Top-Bar area.
Additionally, you can also consider using something like this:
<!-- Header
============================================= -->
<header id="header" class="full-header">
<div class="container">
<div class="header-row py-4">
...
</div>
</div>
<div class="w-100 border-top"></div>
<!-- Sticky Area -->
<div id="header-wrap">
<div class="container">
<div class="header-row">
...
</div>
</div>
</div>
</header>
The First Header Area (.header-row) can have your Parent Company Information. And then the Sticky Area can have the default information according your needs. Here is another example: http://themes.semicolonweb.com/html/canvas/demo-construction.html . If you have any examples of what you are looking for, we can point you to the Template which we already have available or provide you with more information on how you can get started to achieve the example you need.
Hope this Helps!
