Custom gadgets in the sidebar

Sorry, you cannot add your own gadgets to the sidebar, but you can to anywhere on the page, so you may want to think about removing the sidebar and just adding the gadget directly to your page?

The navigational element applies to hundreds and hundreds of pages so putting it on every page is not a reasonable approach.

I am trying to do something like this as well, would love home hints on how.

unfortunately I am finding that there are some limitations within sites that make it somewhat inflexible as a tool for most businesses, such as the inability to have complete control over the navigational elements of the site structure.

It would be nice if sites simply allowed for a text box that didn't wipe or rewrite the object tags and html.

"such as the inability to have complete control over the navigational elements of the site structure"

I want to add "like box" from facebook in the below of the navigator in the sidebar,
It can be helpful my website to get a fan, and all fans will get the update automatic when I put new update.
 
Can Google help on this?
 
and I found the blogger has the useful gatget more than sites.google, I don't know why both of them are google but I don't know why it is difference for the gadget, I know blogger is the blog and sites is for website but I need to share some gadget from blogger in sites.
 
how can I do?

I'm going to have to agree that I feel REALLY stunted by the fact that I can't embed a Facebook iframe for even embed a vimeo or youtube video in the side nav bar. In this age of social media - these are real and absolute needs of any professional site.

I wanted to do the same as @pjumpod. :-(
 
Why is it that Google has functionality to do something on one of its sites, yet hasn't on another? Sorry Steegle but I cannot work out your reasoning that "Google SItes is that a Google Site is always available on a google.com domain, so restrictions are put in place to protect visitors."
 
Personally, I think the real reason is that Google has been on a buying spree of sites like blogger, Youtube etc. and now is in the embarressing situation that some of its portfolio of sites has functionality that others dont. The old phrase about biting off more than you can chew comes to mind :-)

@ cafecumberland The problem you are having tying multiple sites together into one big site would be solved if Google offered sub-sites. I am trying to build an intranet, to replace a SharePoint intranet site, that offers a separate site for each department in our company. I have to make them look like they are all one site through complex linking that needs to be added to each site one at a time. If I could build one site with sub-sites for each department, the built in navigation would work and easily be added by using a template. I can't see why Google doesn't realize that sub-sites are necessary.
