This page presents widget types to be used to display aggregate buckets.

As described in Page Provider Aggregates, you can define aggregates on content views based on Elasticsearch. In order to display and select the buckets returned by an aggregate, new widget types have been added to the platform.

The following picture shows the default search of Nuxeo Platform where you can see a couple of aggregate widget type in action on the left-hand side panel.


Here is a table sumarizing the different type of widget to display aggregate buckets.

All these widget types have an important property in common, selectOptions, which needs to be set with the list of bucket returned by the associated aggregate. This will always be:

<property name="selectOptions">#{contentView.pageProvider.aggregates['xxx'].extendedBuckets}</property>

where xxx is the id of aggregate (see the page Page Provider Aggregates).

As you can see, each widget type is actually available with checkbox or select2.

All select2-based widgets have the following properties:

  • placeholder: The placeholder of the select2 widget. Default is  Select a value .
  • width: The width of the select2 widget default is 100%.

All checkbox-based widget have the following properties:

  • moreLessLimit: By default, only six buckets (i.e. checkboxes) are displayed. If there are more buckets, a 'More'/'Less' link will make show/hide the other buckets. Use this property to change this setting.
  • emptyChoiceMessage: The message to be displayed when there are no returned buckets. Default is  No available result .

User Terms Aggregate Widget Types

Using one of these widget types will force to resolve the bucket key (i.e. the value stored in the document property) as a user id and will display its "Firstname Lastname" if any.

Directory Terms Aggregate Widget Types

Using one of these widget types will force to resolve the bucket key (i.e. the value stored in the document property) as a directory entry and will display its localized label.

These widget types have the specific widget properties:

  • directoryName&nbsp; : The name of the directory from which the entry must be resolved (required)
  • localize : Whether the entry should be localized
  • dbl10n&nbsp; : false (default) means the entry is to be localized from file. true means the directory directly support localization in dedicated columns .

Document Terms Aggregate Widget Types

Using one of these widget types will force to resolve the bucket key (i.e. the value stored in the document property) as a document uuid and will display its title.

Range Aggregate Widget Types

Range aggregates define a set of ranges for which we can define the label to be displayed. This is possible with the use of selectOptions on the widget definition. Here is an example with the range aggregate on  common:size :

<widget name="common_size_agg" type="selectManyCheckboxRangeAggregate">
    <mode value="edit">#{contentView.pageProvider.hasAggregateSupport() ?
      'edit' : 'hidden'}</mode>
  <properties widgetMode="any">
    <property name="selectOptions">#{contentView.pageProvider.aggregates['common_size_agg'].extendedBuckets}</property>
    <property name="localize">true</property>
    <option itemLabel="label.aggregate.size.tiny" itemValue="tiny" />
    <option itemLabel="label.aggregate.size.small" itemValue="small" />
    <option itemLabel="label.aggregate.size.medium" itemValue="medium" />
    <option itemLabel="label.aggregate.size.big" itemValue="big" />
    <option itemLabel="label.aggregate.size.huge" itemValue="huge" />
  <controls mode="any">
    <control name="supportInsideInputWidgetEffects">true</control>
