A About Item Types

Check Box

Displays multiple values as check boxes, enabling the end user to select multiple values. A list of values is required for items displayed as check boxes. The values corresponding to the checked boxes are stored in a single colon-delimited string.

Note: For Yes/No check boxes (that is, a checkbox with only one value), Oracle recommends using a Switch item type.

The following example displays employee names (ename), but returns employee numbers (empno):

SELECT ename, empno FROM emp;

Popup LOV

Displays a text item with a popup list of values icon. When the end user clicks the icon, a popup window appears with a search field, and a list of supported values.

Popup LOV is best suited for large lists since end users can enter search criteria to reduce the available values displayed. For relatively small lists Select List is often better suited.

SELECT ename name, empno id 
   FROM emp

Text Field

Displays the item as a text field.

Page Designer item attributes:

• Settings, Subtype - Select the HTML5 text subtype. This enables devices with on-screen keyboards to show an optimized keyboard layout specific to the subtype, for easier data input. The subtype selection is also used to render an appropriate link with the value of the page item, if it is rendered read only. This attribute does not change the text item, or data entry, when using a physical keyboard.

  Note: This HTML5 feature only works in modern browsers. Older, non HTML5-compliant, browsers ignore this attribute and render the page item as a normal text field.

A disabled text item still displays with the same HTML formatting, unlike an item type of Display Only, which removes the HTML formatting. Disabled text items are part of page source, which enables their session state to be evaluated. Conversely, display only items are not stored in session state.

Text Field with autocomplete

Displays a text field that displays a list of possible values, based on the text already entered by the end user, inline with the text item. The list is further refined as the end user types in more text.

select [displayValue],

Lazy loading retrieves matching records from the database each time the user types a character. Otherwise, all of the list values are loaded on page load. Oracle recommends using Lazy Loading when you have a large select list, as loading a large number of records may impact the time to initially load the page.

• Settings, Maximum Values in List - Enter the maximum number of items to display in the select box. This value can help avoid performance problems by returning too many rows, and also prevent a very large return set when only a few letters have been entered.
