APEX gives you a lot of power and flexibility with its built in wizards. They are very good at
creating the base needs of a general application. This is true with forms. However, the wizards
create everything in the same way, which may or may not be what you want the end form to look
like. In this tutorial we will look at how to alter and better control the form’s appearance and
layout, as well as how to optimize our form somewhat. This tutorial installs it’s own sample data,
so the OEHR sample data is not required, but we reccomend you have it installed if you don’t
already. Our article on APEX Tutorial Preparation and OEHR Sample Data Install covers it’s
installation and creation of a user account for development purposes.

Notes and Resources.
As mentioned in the tutorials first part, the wizards create everything in a form the same way.
By altering the item type we can make the form more compact, as well as easier to use for the
end user. We have a variety of options available to us, from radio groups, to check boxes, to
select lists, as well as others. An empty field is not always the best way to get information.
We discuss the Label Templates, but make no changes in this tutorial. Any label can be altered
by it’s template setting, as well as other options. One thing of some confusion is the
difference between the templates ‘optional label with help’ and ‘required label with help’. The
main difference is that the Required Label option puts a small yellow asterik next to the label.
The number and type of label templates available vary based on which theme you selected for the
We also discuss but make no changes to the buttons in this application. Like all items in the
application, you can alter the appearance, position, label, and functionality of the buttons. We
have allowed the APEX system to place the buttons in this application, but we are free to move
them about if we wanted to.
Running for Update
This application is primarily designed to input new employees. However, if you wanted to see
how some for the conditional settings work, you need it in update form. If you wanted to do this,
you would take the URL of the page (while it’s running, not in the developers edit screen) and
to the end of it add ‘P2_EMP_ID:1’, This will force a value (1) to be assigned to the named item
(P2_EMP_ID) and you will be able to see the data associated with that record. For example, if my
URL was ‘apex.oracle.com/pls/otn/f?p=9659:2:1284393467360777225::::’ I could update a record by
editing it to be apex.oracle.com/pls/otn/f?p=9659:2:1284393467360777225::::P2_EMP_ID:1 which
would allow me to view and update the record for employee 1
