How to Hide or Remove the Quick Launch in SharePoint 2010
Trying to customize SharePoint master page and having so much of problem hide or remove the left navigation in SharePoint 2010. I searched in Google for solutions but it didn’t work well for me.
When I tried to hide the left navigation in SharePoint 2010 from the solutions I got, I was getting a blank space in left side.

Many of the solutions also speaks about adding the code Content Editor but that also gave me a blank space in the left hand side. After long struggle, I made it work by using the code from

This is about the tenth or so post i’ve found on the subject, but none specifies where the “master file” is; not even a file name! Could you please be more specific?
1. Download SharePoint Designer
2. Open your SharePoint site using SharePoint Designer
3. You can see the master pages
If you need more info, please let me know.
Got that, but which file do I edit?
Which master page you want to use?
In this case, I am using v4.Master. If you want you can copy v4.Master and rename to custom.master and try it.
That works, Thanks.
We are migrating our SharePoint customized application to Sp2010, and trying to remove this for few hours! Thanks for your article! Great!!
Thanks for your comments.
Thanks for mentions Aryan, and keep on with your blogging!
Hi,
But what happens when we try to check the web analytics ? The left navigation is hidden in web analytics also, how do i see that ?
No SharePoint Designer Required! I was able to perform the same change more elegantly by placing a hidden HTML Form Webpart on the page which included this code.
It worked like a charm! I also have SharePoint Designer, but using a hidden webpart allows anyone with site edit access to enable or disable this change easily any time. Thanks!
Thank you, this worked on my SP2010 site! Very detailed blog!
Your are my hero !!!! This is the only method that works 100%
It works for me but leaves me a blank space where the navigation is…why
