Customize form in InfoPath 2010 with Custom fields into SharePoint 2010 List

Question

In my SharePoint List I have a custom field which is a filtered lookup.

The thing is that I would like to customize my form in InfoPath 2010 for that list, but I can't because I've got a custom field into it. When I'm trying to edit the list form from SharePoint I get the following error message in InfoPath :

"The SharePoint list form can't be customized with InfoPath because fields of an unsupported data type are marked as required, or because fields are corrupted. In SharePoint, try deleting the columns or editing the column properties to remove the required attribute. - Items (FilteredLookupField)"

This is normal, because it's not supported but is there a way that I could customize that form in InfoPath? If not, tell me how I could do it.

Many thanks.

Unfortunately, InfoPath will not help you there. You can however try to accomplish it in SharePoint Designer as it also offers a customizable, XSLT-based form control you can use.
