If you add a header to a dashboard, it is inserted below the current line of widgets.
Its default text is ‘Header’, and it is presented initially in edit mode (you can change the text, and then click off the header, or hit Return, to leave edit mode).
A mini toolbar is displayed on hovering over a header:
It exposes the following options:
•Edit Header Text: invocation presents the header in edit mode (note that double-clicking the header has the same effect). A header's maximum length is 100 characters. Note that, if required, you can create a header with no text.
•Remove Header: invocation removes the header. This option is protected by an ‘Are You Sure?’ dialog.
As with widgets, you can use drag and drop to re-position headers within a dashboard.
