Defining a Default Launch Element
Depending on the functional requirements of our Domino Web application, you may be required to have a specific Default Launch Element (DLE). The DLE can vary based on the specific needs of your user community or the specific function or design of our Domino Web applications. In this section, we will review several DLE methods and examples.
Application-specific and example DLEs
Application function types often drive the DLE logic because the combination of various Domino design elements are often required to achieve the results that are required by certain types of applications. When we understand the different types of DLEs, we can then properly construct our application-specific DLE. In the following sections, we discuss the various types and examples of DLEs.
Most Domino Web developers are familiar with the the simple DLEs of Web application development: Frameset design elements and Page design elements. While Page Design Element DLEs are still useful and can provide our user community with a viable DLE solution, using Frameset Design Elements have become a depreciated practice.

As stated, the Page Design Element DLE can provide the user community with a perfectly functional solution, but as we extend our Web application development to include external technologies and more advanced user interfaces, we discover that Form design elements often make the more logical choice when defining a Default Launch Element.
In the following sections, we discuss several methods and practices to use Form Design Element DLEs.
The Lotus Notes Help databases are perfect examples of Index DLE applications. These applications launch with a Frameset-like display, typically consisting of an index, or navigator combined with a content body, or main section dedicated to the display of the highlighted/selected content.
As the usage of Frameset Design Elements are depreciated, we architect our DLE toward Web Development Standards, which require the combination of several Domino design elements.
In the above example, we have an index on the left in blue and a content body on the right in red. We can achieve this same layout easily with the following design elements:
1. Create a blank [Navigator Design Element] named "index.html".
2. Create a Form Design Element named "$$NavigatorTemplate for index.html".
3. In the Form Design Element, add your desired user interface elements, objects, and markup.
4. Modify the Database Launch Properties to "Open designated Navigator in its own window" and select the "index.html" Navigator Design Element.
Dashboard DLEs are becoming more and more popular with the advent of portals, mash-ups, and composite application development.
