Since these buttons include HTML structure in your page, they are stylable via CSS. So you can move the popup dialogs with CSS.
Some Code
If you take a closer look at the popups presented by facebook, you will see, that it has some styles attached to it:
The only thing you now have to do is moving this popup via CSS to the correct position.
For example: if you want to hide the comment popup of the like button completely, you can just use this CSS:
.fb_edge_comment_widget.fb_iframe_widget {
display: none;
}
If you now want to move it, you cannot use .fb_edge_comment_widget.fb_iframe_widget
since the element properties (set by JavaScript) will override your CSS. You have to use the span one element lower:
.fb_edge_comment_widget.fb_iframe_widget > span{
right: 300px;
}
This code will move the popup by 300px to the left:
This is not the most beautiful solution (note the small arrow at the top of the box now points to nothing), but it works.
Complete test code:
<!DOCTYPE html>
<html>
<head>
<title>Test</title>
<style type="text/css">
.fb_edge_comment_widget.fb_iframe_widget > span{
right: 300px;
}
#wrap {
width: 650px;
margin: 0 auto;
}
</style>
</head>
