Adding to the pimcore UI

Extending and Modifying the Object Tab

Classes of Object Layout Components

The name of an object class layout element is added to the element's class names as  objectlayout_element_FIELDNAME

e.g. An object panel with the name "myPanel" would have the css class "objectlayout_element_MyPanel"

This comes in handy when you need to style a layout element differently through a plugin.
