Configuration manual for PageSeeder

PSML properties editor


In PSML, a property is a single or multi-value object, typed as either a string, a date or a cross reference.  With no modification, PageSeeder will serve properties in a type-specific editing interface. However, for improved productivity or data quality, the editing interface for properties can be customized. 

To create a custom properties editor, go to the Document Types page under the Dev menu  in the Developer perspective. Go to the Editor Config column and select the row for document type to customize. This will create or open a editor-config.json file that stores the custom editor configuration for one or more of the fragment types in the document type. The configuration details are documented after the Use Case section.


The default PageSeeder editing interface can be specialized according to the @datatype of the <property> element. Examples include:

  • String editor
    • check boxes ("checkbox")
    • select lists ("select")
    • patterns constrained by regular expression ("text")
  • Date editor ("date")
    • date
  • A cross reference editor that is preconfigured to autosuggest only link targets that are:  ("xref")
    • contained by a certain folder structure.
    • with a certain document type or document label.
    • with a certain filename or ID.

Configuration options

The PSML properties editor can be customized using the <editor-config name="PSMLProperties"> element.

<editor-config name="PSMLProperties">
  <field ... />
  <field ... /> 

 The allowed attributes for each <field> are as follows.

AttributeDescriptionDefault value
nameThe name of the property (required).
typeOne of "text", "select", "checkbox", "date", "xref" or "markdown" (required)
labelTo be displayed as a title, next to the editable field.[name]
placeholderText that has been 'ghosted' into the text fields as guidance for the users.
patternA regular expression that constrains the value of the field (property). In other words, to be valid, the text string must conform to the pattern.
autocompleteList the values of other documents as the value of this property (default false)false
uniqueTo flag whether the property value is referenced in other documents (default false)false
readonlyWhether the field should be editable (default false)false


If type="xref" the <field> element can contain one <xref-config> element with the same content as for the XRef config except that @name is optional.

If @name is specified then the configuration from the PSML XRef config for the project (xref-config.xml) with the same name is used and this <xref-config> element should be empty.


As properties can not contain <blockxref> only options for <xref> should be used in the xref config. Also the @fragmenttype attribute on <xref-config> is ignored in the properties editor.


If type= "select" or "checkbox" the <field> element can contain one or more <value> elements which contain the allowed values for the property.


The field type in the properties editor configuration define the input type for the property and is related to the @datatype attribute of the property.



The text type will display a simple input box for text to be entered manually. The placeholder option can be used to display a hint in the text box when no value has been specified.

The pattern option can specify a regular expression that the value must match to be submitted. This can be useful mechanism to constrain the format or possible values.


The select type will display a simple drop-down list. Only one value can be selected by the user. The list of possible values can be set using the values option as a JavaScript array. 


The checkbox type will display a list of check boxes so that multiple values can be selected. The list of possible values can be set using the values option as a JavaScript array. Normally the PSML property should have @count="n" or @multiple="true", but if @count="1" and there is no @multiple  the options will be comma separated in the value attribute (note: @count is deprecated as of PageSeeder 5.9800).


The date type will provide a date picker to the user and store the value as ISO8601 (yyyy-mm-dd).


The XRef type allows users to set or edit cross references within a label.


The markdown type is for formatted text, see markdown.


This option is designed to promote better consistency in values used for a property. It is less restrictive than the select input type, but provides suggestion from usage data that is more useful than free text or suggestions from the browser (which are restricted to the user & machine).

It only applies to fields of type text - both single and multi-valued.

The editor will list the values previously used for that property so that the user can select one of them. The scope of the lookup is based on the property name but not the document type within the current group.


   <field name="category" type="text" autocomplete="true" />


This option is designed to prevent users entering duplicate values in properties which should be considered unique.

It only applies to single valued fields of type text and for values of at least 3 characters.

The editor will perform a lookup in the index for that specific property to check whether any other document uses the same value to determine whether the field value is unique.

The editor also list values starting with the same string which have already been used. For example, if '1234' and '1235' already exist, and the user types '123' both values will be displayed below in red with the name of documents these values are used in.

The scope of the ID is based on the property name but not the document type within the current group. This could be changed in the future to reduce the scope of uniqueness within documents of the same type rather than all documents or expand it to other groups.

This option defaults to false and takes precedence over autocomplete.


    <field name="isbn" type="text" unique="true" />


This option is used to prevent some values from being editable. It is useful when values have been previously generated by a template or uploaded.

It could also be used when shared documents include some properties that can be edited by one group but not the other. But remember that if the permissions allow users to edit the document, PageSeeder will not prevent the property from being modified

It only applies to date, text and xref input types.

This option defaults to false and takes precedence over autocomplete and unique - they are ignored if specified.


    <field name="payment" type="text" readonly="true" />


If you're having trouble getting your configuration file to work, check the following:

  • The name of the file must be editor-config.xml  if you have used the developer tools, it should already be the case.
  • The file must be in the correct location template/[project]/psml/[document type]/  if you have used the developer tools, it should already be the case.
  • Click the Validate All button on the Dev > Document config page which will validate the contents of all config files.

Sample config

<editor-config name="PSMLProperties">
    <field name="author"
    <field name="category"
    <field name="in-stock"
           label="In Stock">
    <field name="available-date"
           label="Available Date"/>
    <field name="isbn"
           placeholder="Enter a valid ISBN 13
                       number (97xxxxxxxxxxx)"
    <field name="publisher"
           placeholder="Lookup publisher"/>

Before the properties editor can display the fields it requires some default content in the PSML which is usually added to the PSML document template for that document type.

The sample config above would require something similar to the following default content:

<properties-fragment id="2">
    <property title="Author"
              count="n" />
    <property title="Category"
              count="n" />
    <property title="In Stock"
              name="in-stock" />
    <property title="Available Date"
              datatype="date" />
    <property title="ISBN"
              name="isbn" />
    <property title="Publisher"
              datatype="xref" />
