Portal Predefined Settings
The portal defines some settings that allow the theme to determine certain behaviors. So far there are only two predefined settings but this number may grow in the future. These settings can be modified from liferay-look-and-feel.xml.
If set to false, the portal will turn off borders by default for all the portlets. The default is true.
<setting key="portlet-setup-show-borders-default" value="false" />
This default behavior can be overridden for individual portlets using:
• Portlet CSS popup setting
This setting is used by the Navigation portlet to determine the CSS class name of the list of pages. The value must be a comma separated list of valid bullet styles to be used.
<setting key="bullet-style-options" value="classic,modern,tablemenu" />
The bullet style can be changed by the user in the Navigation portlet configuration. The chosen style will be applied as a CSS class on the <div> containing the navigation. This class will be named in the following pattern:
... CSS selectors ...
Here is an example of the HTML code that you would need to add style through CSS code. In this case the bullet style option is modern:
<div class="nav-menu nav-menu-style-modern">
<ul class="breadcrumbs lfr-component">
