Creating Display Templates

For every data definition, you can create as many displays as you need. If you’ve created a form template that doesn’t show all the fields of a particular data definition in the data list’s form view, you probably don’t want to display those fields in the list view, either. Modify the list view using Display Templates.

As with form templates, you can create display templates from the Dynamic Data Lists app in Site Administration or the Dynamic Data Lists Display widget.

Follow these steps to create a display template from Site Administration:

  1. Open the Menu (Menu) and expand your Site’s menu (the Site Administration menu). Then select ContentDynamic Data Lists. This opens the Dynamic Data Lists screen. A table lists any existing dynamic data lists.

  2. Click the Options button at the top-right (Options) and select Manage Data Definitions. The Data Definitions screen appears. A table lists existing data definitions.

  3. Click the definition’s Actions button (Options) and select Manage Templates. This lists the definition’s templates.

  4. Click the Add button (Add) and select Add Display Template.

  5. Give the template a name, expand the Details section of the form, and give it a description. Also in the details section of the form, select the templating language to use from the Language selector. You can choose FreeMarker, or Velocity.

  6. In the Script section of the form, create your template in the editor using the templating language you chose in the previous step. The palette to the left of the editor contains common variables. Click a variable to insert it in the editor. The editor also autocompletes. In a FreeMarker template, type ${, which opens an autocomplete list of common variables. Select a variable to insert it in the editor. Alternatively, you can upload a complete script file via the Browse button below the editor.

  7. Click Save when you’re done creating the template.

Alternatively, you can use the Dynamic Data Lists Display widget to create display templates:

  1. Follow the instructions in the Creating Data Lists article for adding and configuring the widget in a site page. Make sure to configure the widget to show the list’s definition you’re making into a template.

  2. Click the widget’s Add Display Template button. This opens the same form as above for creating a display template for the list’s definition.

Display Template Editor

Helper variables are available in the template editor. These provide access to most of the data that you’ll use in creating Display Templates. The variables under the heading Data List Variables let you inject specific information about the data definition the template is being created for:

Data Definition ID: reserved_ddm_structure_id

Data List Description: reserved_record_set_description

Data List ID: reserved_record_set_id

Data List Name: reserved_record_set_name

Template ID: reserved_ddm_template_id

Inside a template, these variables give the ID for the record set as well as the name, description, and data definition.

Display the list of records by retrieving them and assigning them to the handy records variable. Retrieve the list’s records from DDLDisplayTemplateHelper, which contains these functions:

getDocumentLibraryPreviewURL

getHTMLContent

getLayoutFriendlyURL

getRecords

renderRecordFieldValue

DDLDisplayTemplateHelper performs common tasks. Use the getRecords method to access a data definition’s entries and assign them to a records variable:

<#assign records = ddlDisplayTemplateHelper.getRecords(reserved_record_set_id)>

This fetches the records of the associated data list. You haven’t done anything with them yet, so your display is still empty. To list all the records, use the Data List Records helper in the sidebar of the template editor. Remember to place your cursor in the proper place in the template editor window, then click Data List Records. This code appears at the cursor:

<#if records?has_content>
    <#list records as cur_record>
        ${cur_record}
    </#list>
</#if>

This default code snippet spits out everything in the database for the given data definition, which is ugly and practically useless:

{uuid=52c4ac1c-afe7-963c-49c6-5279b7030a99, recordId=35926, groupId=20126, 
companyId=20099, userId=20139, userName=Test Test, versionUserId=20139, 
versionUserName=Test Test, createDate=2018-07-26 14:31:51.056, 
modifiedDate=2018-07-26 14:31:51.058, DDMStorageId=35927, recordSetId=35922, 
recordSetVersion=1.0, version=1.0, displayIndex=0, lastPublishDate=null}

Here’s a simple example template that uses a list based on the embedded Contacts data definition, and only displays the Company Name and Email fields in a bulleted list:

<#assign records = ddlDisplayTemplateHelper.getRecords(reserved_record_set_id)>

    <h1>Here are contacts by company name and email address.</h1>

    <#if records?has_content>
        <#list records as cur_record>
            <ul>
                <li>
                    <#-- The below gets the Company field and wraps it in an <em> tag -->
                    Company Name: <em>${ddlDisplayTemplateHelper.renderRecordFieldValue(cur_record.getDDMFormFieldValues("company")?first, locale)}</em><br /> 
                    <#-- The below gets the Email field  and wraps it in an <em> tag --> 
                    Email: ${ddlDisplayTemplateHelper.renderRecordFieldValue(cur_record.getDDMFormFieldValues("email")?first, locale)} 
                </li> 
            </ul> 
        </#list> 
    </#if>

Here’s what it looks like:

Now you’re prepared to make data lists beautiful using Display Templates.
