Column definition

Columns define what content is displayed in tree and list views in the browser subapp.

This column definition is part of the Magnolia 6 UI framework. The fully qualified class name is info.magnolia.ui.contentapp.configuration.column.ColumnDefinition.

Example definitions

Simple column definitions

  • Title column

  • Date column

columns:
  jcrName:
    $type: componentColumn
    nodeTypeToComponent:
      mgnl:page:
        icon: icon-file-webpage
        showPath: true
columns:
  mgnl:lastModified:
    $type: dateColumn

Columns with filter definitions

  • With a default filter value

  • With a checkbox filter

columns:
  value:
    filterComponent:
      $type: textField
      defaultValue: '10'
      converterClass: info.magnolia.ui.editor.converter.StartsWithFilteringModeConverter`
columns:
  mgnl:activationStatus:

      $type: comboBoxField
      emptySelectionAllowed:
      datasource:
        $type: optionListDat
        options:
          - name: true
            value: true
            label: Featured
columns:
  destination:
    filterComponent:
      $type: comboBoxField

        workspace: category

Column properties

Property Description

class

required (unless $type is used)

The column definition class reads the column configuration and displays the column accordingly. The class must implement the info.magnolia.ui.contentapp.configuration.column.ColumnDefinition interface. You can write your own class or use one of the ready-made classes. See Column types for possible values.

$type

You can use this as a shortcut for class if the definition class is annotated with info.magnolia.ui.contentapp.configuration.column.ColumnType. The proper value is defined by the annotation.

Example class annotation
@ColumnType("dateColumn")
public class DateColumnDefinition extends ConfiguredColumnDefinition<Date> {
...
}

To use the $type property in YAML, see Example definitions.

type

required, default is java.lang.String

Data type of the column. Use the fully qualified class name. See PropertyType for possible values.

A default type is typically hard-coded in each definition class. You only need to add this property if you want to override the default implementation.

Make sure that type is set to a value that matches the type of data you entered (for example, java.lang.Long for long values).

You can’t configure this property through YAML but it can be used in your Java code.

name

optional, default is parent node name

Name of the column.

label

optional

Text displayed in the column heading. The value can be literal or a key of a message bundle.

If you don’t provide the property, Magnolia falls back to a generated i18n key.

descriptionGenerator

optional

Generates a description for the column.

You can’t configure this property through YAML but it can be used in your Java code.

editable

optional, default is false

When true, the column can be edited inline. You can double-click a cell to edit its value.

You can’t define defaultAction and use inline editing at the same time.

editor

optional

Defines the inline editor component. For this to work, you have to set editable to true. See the info.magnolia.ui.contentapp.configuration.column.ColumnEditorDefinition interface.

     field

required, default is textField

Type of the field definition item. See Field types for possible values.

     availability

optional

Outlines when inline editing is permitted. See Action availability for more information.

Availability is resolved against the selected row, not the selected column or property.

filterComponent

optional

Adds a filter field to the column. Only text, checkbox and combobox fields are supported (see Example definitions). The default value and converter of combobox field are not supported.

A node identifier is applied to filtering if the field value is javax.jcr.Node. That is, if the destination column in Example definitions is configured with jcrDatasource, the combobox field options will be populated with javax.jcr.Node.

Use converterClass: info.magnolia.ui.editor.converter.StartsWithFilteringModeConverter to change the filtering mode from CONTAINS to STARTSWITH to improve the performance of textField filters in huge JCR workspaces.
Column filtering is not supported in REST-based elements of the UI.

expandRatio

optional

Defines the ratio with which the column expands. By default, all columns expand equally.

maximumWidth

optional

Defines the maximum allowed pixel width of the column when it is set to expand.

minimumWidth

optional

Defines the minimum guaranteed pixel width of the column when it is set to expand.

minimumWidthFromContent

optional, default is false

Sets whether the width of the content in the column is the minimum width of the column. When false, the column shrinks down to the width defined in minimumWidth if necessary.

width

optional

Defines the width (in pixels). When set, overrides any configuration from expandRatio, maximumWidth and minimumWidth.

sortable

optional, default is true

When false, the column cannot be sorted.

renderer

optional, default is com.vaadin.ui.renderers.TextRenderer

Class extending Vaadin AbstractRenderer.

com.vaadin.ui.renderers.ComponentRenderer is used by columnComponent. info.magnolia.ui.contentapp.configuration.column.renderer.DefaultDateRenderer is used by dateColumn.

You can’t configure this property through YAML but it can be used in your Java code.

valueProvider

optional

Class extending Vaadin ValueProvider.

You can’t configure this property through YAML but it can be used in your Java code.

We don’t recommend configuring type, renderer and valueProvider through YAML.

Rather, create a custom column definition instead to prevent misconfiguration errors such as configuring a correct renderer but a wrong type:

public class ProgressColumnDefinition<T> extends ConfiguredColumnDefinition {
    public ProgressColumnDefinition() {
        setType(Double.class);
        setRenderer(ProgressBarRenderer.class);
    }
}
columns:
  scale:
    class: my.package.ProgressColumnDefinition
