We demonstrate how element settings are specified and set by a special formatter for an demo article content item. The formatter's configuration defines different element settings used by the formatter to format the same article in many different ways.

The result

Below you see the same demo article content, but with different element settings.

If you are in offline mode, you'll see edit points on the demo articles. Hover over the edit points and click the small gear wheel that appears to edit the element settings. See how the articles appearance changes if the settings are altered.

 

Element Settings 1

8/29/14

Hover over the edit point and choose the element settings button from the menu that appears. There you can change my appearance.

Settings values:

Text field "Text" = Element Settings 1
Check box "Show Image" = false
Date picker "Date" = 1409268360000
Radio buttons "Date Format" = date

Element Settings 2

8/7/14 12:56 PM

Hover over the edit point and choose the element settings button from the menu that appears. There you can change my appearance.

Settings values:

Text field "Text" = Element Settings 2
Check box "Show Image" = true
Date picker "Date" = 1407408960000
Radio buttons "Date Format" = both
 

Example resources and the interesting spots

For the above example a special formatter for the "Demo Article" content was created and configured. In the formatter configuration the element settings are configured, while in the formatter, the settings are read. Depending on values of the settings, the content is formatted differently.

The configuration is done in the "Supported Settings" tab of the formatter configuration. See the tab "Supported Settings" in the configuration below.

The Settings that are configured in the formatter configuration shown above can be accessed in the configured formatter via their "Setting name".

Note that there are two ways to access element settings:

  • Via EL: ${cms.element.settings['setting name']}
  • Via a tag: <cms:elementsetting name="setting name" default="defaultvalue" />
