Hi paligula,
The only way I have ever managed to (easily) sort this is to give a negative value to the left margin in the css rule for the 'fullColumnGroup'.
In your CSSFormBuilder folder there is a css file that ends with '_Default.css'. If you open that file, and search for 'fullColumnGroup', you should find something like the following rule (the name may be a bit different depending on which presets you used) :
form.NewFromBlank_Default div.fullColumnGroup {
width:764px;
padding-bottom:0;
padding-top:10px;
display:inline;
float:left;
}
Enter a negative value for the left margin, by adding the line:
margin-left: -200px;
form.NewFromBlank_Default div.fullColumnGroup {
width:764px;
padding-bottom:0;
padding-top:10px;
display:inline;
float:left;
margin-left: -200px;
}
and see if that does it. Play with the size of the (negative) margin.
