After posting a few times on the wordpress.org theme support section regarding Catch Kathmandu being full width. I noticed other people were having the same issue as I was. To me the option for no side bar means full width. So I thought I would try make a my own custom page template, and I succeed and the custom page template worked nicely. However when the Catch Kathmandu theme updates I lost my theme as a mod later pointed out to me. I was told and saw other people were being told in order to keep the page template you would have to create your own child theme.
So I did. I tried it out it works nice. The only thing I noticed is that the header logo went away once I activated the child theme. This was an easy fix I just re-updated my logo and everything worked fine. If you want to try my child theme you can do so by the below link. Just note this is my first child theme, it was only designed to make a full width page in the Catch Kathmandu theme.
Some make basic things about it out. In order for it work you of course have to the Catch Kathmandu theme installed first. Then to use it, simply go to the page you want to make full width in the admin view of WordPress, Then in the Page Attributes box select the “Ryan is Awesome” in the template box. You can rename the template if you want to by editing the fullwidth.php file. If you have any basic questions feel free to comment blow.
Also note that the Pro version has this feature in it with along list of other features. Their version is fully supported this one is not.
