Ok, so:
how to do a 2 column form with Forme 1.0.3:
1. in the Form Style tab, change the \"Edit the form style\" from:
<div align=\"left\" style=\"width:100%\" class=\"componentheading\">{formtitle}</div>
<form name=\"{formname}\" id=\"{formname}\" method=\"post\" action=\"{action}\" {enctype}>
<table width=\"100%\" border=\"0\" cellpadding=\"0\" cellspacing=\"0\" class=\"forme\">
{formfields}
</table>
</form>
to
<div align=\"left\" style=\"width:100%\" class=\"componentheading\">{formtitle}</div>
<form name=\"{formname}\" id=\"{formname}\" method=\"post\" action=\"{action}\" {enctype}>
<table width=\"100%\" border=\"0\" cellpadding=\"0\" cellspacing=\"0\" class=\"forme\">
<tr><td><table width=\"100%\" border=\"0\" cellpadding=\"0\" cellspacing=\"0\" class=\"forme\">
{formfields}
</table>
</td></tr></table>
</form>
2. Apply changes
3. After the second field add a new field like this:
Field Id: free1
Field type: free text
Field style:
</table></td><td><table width=\"100%\" border=\"0\" cellpadding=\"0\" cellspacing=\"0\" class=\"forme\">
That worked for me. Let me know if you managed to do it.
