# Highlighting in the configurator

When using the Rubens Configurator on a desktop, we provide highlighting in the UI which is shown every time the user hovers over components of a configuration. This highlighting is a white border that is displayed around the affected component.

However, you can define an individual highlighting behaviour for your configurators. There are three different states for the highlighting behaviour in the configurator which you can set in your configurator settings. You can use the URL parameter highlighting or set the behaviour in [the tenant settings](/rubens/rubens-admin/help/administration.md#tenant-settings) in Rubens Admin. Here are the possible options available:

`smart`: Highlighting is enabled if there are add-ons available for the configurator. If there are no addons available, the highlighting is disabled. This is the default behaviour.

`off`: Highlighting is disabled for all cases regardless of addons being available.

`always`: Highlighting is enabled for all cases regardless of addons being available.
