User Defined Fields
If you have set up inventory item user defined fields, they may be used on your Webstore site.
When setting up your user defined fields, define each with 01, 02 and the like, in the name so that they appear at the very top. This also means that the tags (udf1, udf2 and the like) will relate to these first user defined fields.
Within the categorystockitem.ecd include template, you can add a <Greentree ecom stockitem udf1> tag if 1 is the position down from the top as listed on the form.
You can exclude Webtext around each UDF such as: categorystockitem:udf1:1:Text here:.
