Menuing is facilitated with the Dynamic Menu Add-on. It creates the HTML necessary to produce flyout menuing in many configurations. In addition, it generates the styles to produce a generic menu system.
To customize the Dynamic Menu, start by dropping the Dynamic Menu add-on on a template or content page, and render the page (display it). The system will automatically create the necessary records for the Default menu.
To create a different menu, turn on Advanced Edit, and click the Instance Options tool above the Dynamic Menu Add-on. From here, you can select any existing menu settings record, or create a new one.
At this point you can turn on editing, and edit the menu settings record, or add sections to the menu.
In the Menu record, there are several settings that effect the type of HTML that will be produced, and a tab to create or modify the styles delivered with that HTML. There are several styles selectors required for a dynamic menu. To differentiate one menu instance from another, a style 'prefix' is used. For instance, If you choose your prefix as "topNav", each of the five class selectors necessary for the menu should start with the prefix "topNav", like topNavButton, topNavPanel, etc.
I am using the example of a menu using the style prefix eventMenu
A - .eventMenuButton defines what the "button" of the menu looks like
B - A.eventMenuButton defines what an anchored button on the menu looks like (A and B will almost always have identical attributes)
C - .eventMenuPanel defines attributes of the panel that flys out
D - .eventMenuPanelButton defines attributes of the buttons within the panel (background applied here will lay over top of the panel)
E - .eventMenuDelimiter defines what the delimiter attributes are (delimiter is defined in the Dynamic Menu record example here is a |).
