In oracle application framework page, to provide the functionality to hide and show the items under a header we use HideShowHeader region.
In both the case of toggling i.e. hidden or shown header text will remain as it is.
In HideShowHeader region we can add items as we add in Header region.
Please refer Header region for more information on the properties of Header region.
Corresponding web bean: OAHideShowHeaderBean
Labeled Field Layout In OAF
The labeledFieldLayout region lays out its children in columns; one column is for the “labels” and the other for the “fields“, with a gap in between.
The children are laid out across and down, the first child in each row takes the “label” position and the second child takes the “field” position. The contents of each row are centered in the available space.
The “labels” are always right aligned, and the “fields” left aligned.
With multiple columns, the children continue to be layed out across and down. For example, with two columns, the third child will be used as the label for the first row and second column.
It also has support for the inline messaging beans where each inline messaging bean will automatically occupy both a “label” and “field” position.
Corresponding web bean: OALabeledFieldLayoutBean
Note: The labeledFieldLayout component has been deprecated; use the messageComponentLayout component instead. Please refer to the messageComponentLayout section for information about messageComponentLayout.
List Of Values In OAF
A listOfValues region is rendered in a separate modal dialog containing a complex list of possible values that can be selected as a valid value for an entry field on a transaction page or a field within a table. Refer to the messageLovInput section for information on the properties of messageLovInput.
A listOfValues region is rendered as a popup of separate OAF page region containing a list of possible values, any of which can be selected as a valid value for an entry field on a transaction page or a field within a table.

Message Component Layout In OA Framework
In oracle application framework page OAF messageComponentLayout is the most widely used region to hold components.
It is restricted to message components, and it does not allow other regions to become its child.
The components, which are child of OAF messageComponentLayout region, will have, prompt of the component will be right (end) aligned and the text field will be left aligned.
It serves the multiple column display of components in an OA framework page and also satisfies the standard UI guidelines.
It is recommended that we should not display more than 3 columns in respect to follow the UI guidelines.
In the OAF messageComponentLayout the spacing between the components are according to the Oracle BLAF UI guidelines.

Navigation Bar In OA Framework
In oracle application framework OAF NavigationBar is used to navigate to the next or previous set of records.
You might have mostly saw NavigationBar attached with the table or advance table.
Suppose you have run a BC4J VO query that retrieved more than 10 records to be displayed in a table.
Then a NavigationBar will appear at the top and bottom of the table. By using the NavigationBar link you can display the next 10 records, which are retrieved from the query.
NavigationBar can also be seen in the Hgrid region, in case we expand a node and the child retrieved are more than the record limit, that time we have to use NavigationBar link.
Note: No need to declare NavigationBar functionality explicitely.
