Renaming Columns
If you want to rename one or more columns, add a CATNls file with the feature chooser name to the resource container of the know-how apps component. The new column names must be entered as follows: Original_Name="New_Name". The original names are those you can find in the Presented Attributes attribute (separated by commas) of the Feature Chooser. Use Import Files to add this file to the component. In the example below, the CATNls file name is FeatureChooser1.CATNls.

Adding an Icon

To add an icon, enter an icon name in the columnName_Icon attribute. In the example below, the first feature of the chooser is the icon named MyOwnIcon. 

set f= NewFeatureChooser\ChosenItems[1]
f.SetAttributeString("Name_Icon","MyOwnIcon"

You can add icons dynamically on selection events and have the icons changed when you click the features. To do so, create a VolatileInstance and add attributes for the icon.
