+### Custom Field Bindings
+
+If you are using custom field names, you must ensure their binding for each level. Otherwise, the PanelBar will not render items where the field bindings are missing. 
+
+For that purpose, you must do either of the following:
+
+* Add one `TelerikPanelBarBinding` without a level to set the default bindings.
+* Add `TelerikPanelBarBinding` for each level where you explicitly set the field bindings to your custom fields.
+
 ### Multiple Level Bindings
 
 You can define different binding settings for the different levels of nodes in the PanelBar. With this, the children of a node can consume a different field than their parent, and this may make your application more flexible. If you use [hierarchical data binding](slug:panelbar-data-binding-hierarchical), the children can even use a different field or model from their parent.
