Question

i have a simple question.
Is there a simple config file or line that can be edited in order to achieve this:
I need that constraints from Alfresco content model have an empty field (like “unselected”) in Advanced Search and Edit Metadata forms.
So a constraint of:

<constraint name="custom:customList" type="LIST">
            <parameter name="allowedValues">
                <list>
                    <value>first type</value>
                    <value>second type</value>
                </list>
            </parameter>
        </constraint>

I need to view these in a “SELECT” form but with the first selection empty, like:

   <select>
          <value></value>
          <value>first type</value>
          <value>second type</value>
   </select>

Hope I made that clear.
P.S. I don’t want to insert a in the custom content model XML file. There should be another way to achieve this.
Thanks to all.

You need to override the presentation logic, i.e. customize or create a new form control template. The default one is implemented in selectone.ftl, you can customize it or start from it for a brand new control template which you can later assign to your metadata field in the forms configuration.
