How to set portlet preference in theme?

You can supply preferences for your embedded portlet as well.  Liferay provides a built-in VM variable called$velocityPortletPreferences for this purpose.

$velocityPortletPreferences is a Map<String, String>.  For each preference, pass its key string plus the value you desire.  The key may be one of Liferay’s built-in portlet preference keys, or (for plugin portlets) one of your own that your portlet knows how to interpret.

#set ($VOID = $velocityPortletPreferences.setValue(‘display-style’, ‘1’))
#set ($VOID = $velocityPortletPreferences.setValue(‘portlet-setup-show-borders’, ‘false’))}}}
