How To Create a List

To create a list you:

Create the list by running the Create List Wizard.
Add list entries by either creating them from scratch or by coping entries from an existing list. If you copy a list and it contains list items or entries, the list entries are also copied.
Add the list to a page by creating a List region.

How you perform these steps is a personal preference. You can perform all three when you run the Create List Wizard. Alternatively, you can perform these steps one at a time.

3. Region Template - If creating a new region, select a region template.
4. Click Create.

Tip:

You can also create a list under Shared Components on the Page Definition. To learn more, see "Accessing the Page Definition", "Editing a Page in Tree View", and "Editing a Page in Component View"

Adding List Entries and Sublists

Once your list is created, you must add entries to it. You can add list entries from scratch, copy a list entry from within a list, or copy existing entries from one list to another.

You can also create hierarchical lists that contain sublists. To create a hierarchical list, you must:

Select a list template that supports hierarchical lists. To determine which list templates support hierarchical lists, look for templates having the naming convention "with Sublist."
Select a Parent List Item when you create each list entry.

Adding Entries or Sublists from Scratch

To add an entry or sublist from scratch:

Navigate to the Lists page:
1. On the Workspace home page, click the Application Builder icon.
2. Select an application.
3. On the Application home page, click Shared Components.
4. Under Navigation, select Lists.
  
  The Lists page appears.
Select a list.

The Entries by List page appears.
Click Create List Entry.
Under Entry:
1. Parent List Entry - If applicable, select the parent for this list entry. Use this attribute if you are creating a hierarchical list that will contain a sublist.
  
  Note this attribute does not appear if you are creating the parent list entry.
2. Sequence - Indicate the order in which list the list entry appears. The sequence determines the order of evaluation.
3. Image - Identify the file name for the image used to display this list entry. List templates control this attribute.
4. Attributes - Identify the image attributes (such as width="12" height="12") for the list element image.
  
  Use the #LIST_LABEL# substitution string to reference the list label text. This substitution string allows for the title image attribute to be automatically set based on the value of the list label text. For example:
```
title="#LIST_LABEL#"
```
5. List Entry Label - Enter the label text for this link.
Specify a target location.

If the target location is a URL, specify the following:
- Target Type - Select URL.
- URL Target - Enter a URL. For example:
```
http://www.yahoo.com
```
If the target location is a page:
1. Target Type - Select Page in this Application.
2. Page - Specify the target page number.
  
  You can also select reset pagination for this page. Selecting this option causes the page to return to the first set of data meeting a user's new query.
  
  You can also select Printer Friendly. Selecting this option displays the target page using the application's Printer Friendly template. Printer friendly templates optimize a page for printing. "Changing the Default Templates in a Theme" and "Optimizing a Page for Printing".
3. Request - Enter text to set the built-in application item REQUEST. This is also the item that is set with the name of a button that was clicked.
4. Clear Cache - Specify the page numbers on which to clear cache. To learn more, see item Help. See "About Field-Level Help".
5. To set session state (that is, give a listed item a value):
  - Set these items - Enter a comma-delimited list of item names for which you would like to set session state.
  - With these values - Enter a comma-delimited list of values for the items specified in the previous step.
    
    You can specify static values or substitution syntax (for example, &APP_ITEM_NAME.). Note that item values passed to f?p= in the URL cannot contain a colon. Additionally, item values cannot contain commas unless you enclose the entire value in backslashes (for example, \1234,56\).
Under Current List Entry:
1. List Entry Current for Pages Type - Specify when this list entry should be current based on the page type.
  
  List items can be current or non-current. Current list items use the current template; non-current list items use the non-current list item template. The actual condition and templates are defined in subsequent attributes.
2. List Entry Current for Condition - Based on the selection above, define a condition to evaluate. When this condition is true, then the list item becomes current. To learn more, see item Help. See "About Field-Level Help".
For Conditions, specify the appropriate information to make the list entry conditional.
Under Authorization, you can specify an authorization scheme.

This authorization scheme must evaluate to TRUE in order for this component to be rendered or otherwise processed.
Under Configuration, select a build option for this component.

Build options are predefined settings that determine whether components within an application are enabled.
Under Click Counting, you can specify if you want the list entries to be included in the click count.

If this is a link to an external page, such as www.google.com, you can count clicks. For more information, see "COUNT_CLICK Procedure" in Oracle Application Express API Reference.
To specify additional attributes, use the User Defined Attributes section. For example, the following adds a tabindex and accesskey.
```
tabindex="15" accesskey="D"
```
When you are finished defining list attributes, click Create or Create and Create Another.

Copying List Entries Between Lists

You can copy list entries from one list to another.

5. Under Navigation, click Lists.
  
  The Lists page appears.
Select the list to copy.
On the Tasks list, click Copy List Entries from one List to Another.
From Copy List Entries, select the list to copy to and click Next.

Copying a List Between Applications

You can copy a list from the current application or from another application.

To copy a list:

Navigate to the Lists page.

Follow the online instructions. To learn more, see item Help. See "About Field-Level Help".

Adding a List to a Page by Creating a Region

Once you create a list and list entries, the next step is to add it to a page by creating a region and specifying the region type as List.
