title: Customize form in InfoPath 2010 with Custom fields into SharePoint 2010 List
body: <p>In my SharePoint List I have a custom field which is a filtered lookup.</p>
  
  <p>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 :</p>
  
  <blockquote>
    <p>"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)"</p>
  </blockquote>
  
  <p>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.</p>
  
  <p>Many thanks.</p>
