Each page can have any number of regions. The content of a region is determined by the region source. For example, a region may contain a report based on a SQL query you define, or it may contain static HTML.</p> <p>You control the appearance of a region through a specific region template. You can use regions to group page controls (such as items or buttons). You can also create simple regions that do not generate additional HTML, or create elaborate regions that frame content within HTML tables or images.</p> <div align="center"> <div class="inftblnotealso"><br /> <table class="NoteAlso oac_no_warn" summary="" cellpadding="3" cellspacing="0"> <tbody> <tr> <td align="left"> <p class="notep1">See Also:</p> <ul> <li> <p><a href="ui_region.htm#CHDCIJJE">"Understanding Regions"</a> for information about creating and editing regions</p> </li> <li> <p><a href="http://www.oracle.com/pls/db112/lookup?id=ADFNS"><span class="italic">Oracle Database Advanced Application Developer's Guide</span></a> for information about developing Web applications with PL/SQL</p> </li> <li> <p><a href="http://www.oracle.com/pls/db112/lookup?id=ARPLS"><span class="italic">Oracle Database PL/SQL Packages and Types Reference</span></a> for information about htp packages</p> </li> </ul> </td> </tr> </tbody> </table> <br /></div> <!-- class="inftblnotealso" --></div> </div> <!-- class="sect3" --> <a id="CHDCEBEI" name="CHDCEBEI"></a> <div class="sect3"><!-- infolevel="all" infotype="General" --> <h2><a name="HTMDB25120" id="HTMDB25120"></a>Butto<a id="sthref537" name="sthref537"></a><a id="sthref538" name="sthref538"></a>ns</h2> <p>As you design your application, you can use buttons to direct users to a specific page or URL, or to enable users to submit a page. When you submit a page, the Application Express engine posts or processes information. A button can be implemented as an HTML button, an image, or by using a template. Buttons can be placed in predefined region template positions or among items in a form.</p> <div align="center"> <div class="inftblnotealso"><br /> <table class="NoteAlso oac_no_warn" summary="" cellpadding="3" cellspacing="0"> <tbody> <tr> <td align="left"> <p class="notep1">See Also:</p> <a href="bldapp_but.htm#CHDGHIGG">"Creating Buttons"</a></td> </tr> </tbody> </table> <br /></div> <!-- class="inftblnotealso" --></div> </div> <!-- class="sect3" --> <a id="CHDBGGJH" name="CHDBGGJH"></a> <div class="sect3"><!-- infolevel="all" infotype="General" --> <h2><a name="HTMDB25121" id="HTMDB25121"></a>Items<a id="sthref539" name="sthref539"></a><a id="sthref540" name="sthref540"></a></h2> <p>Items are HTML form elements such as text fields, select lists, and check boxes with an associated session state. Item attributes affect the display and behavior of items on a page. For example, these attributes can impact where a label displays, how large an item will be, and whether the item will display next to, or below the previous item.</p> <p>There are two categories of items: page items and application items. <span class="bold">Page-level items</span> are placed on a page and have associated user interface properties, such as Display As, Label, and Label Template. <span class="bold">Application-level items</span> are not associated with a page and therefore have no user interface properties.
