Usage

This function dynamically creates tabs in a tabbed layout; it is equivalent to putting a cflayoutarea tag inside a cflayout tag with a type attribute of tab. The configuration parameter defines tab characteristics; it can have any or all the following entries:

Entry	Default	Description
align	The cflayout tag align attribute value	Specifies how to align child controls within the layout area. The following values are valid: center justify left right
callbackhandler		A function that is called when the layout tab body has loaded. This function must not take any arguments.
closable	false	A Boolean value specifying whether the user can close the window. If true, the tab has an X close icon.
disabled	false	A Boolean value specifying whether the tab is disabled, that is, whether user can select the tab to display its contents. Disabled tabs are grayed out. Ignored if there is a true selected entry.
errorHandler		A function that is called if an error occurs in loading the tab body. This function must take two arguments: The HTTP status code, or -1 if the error is not an HTTP error An error message
inithide	false	A Boolean value specifying whether the tab is initially hidden. To show an initially hidden tab, use the ColdFusion.Layout.showTab function.
overflow	auto	Specifies how to display child content whose size would cause the tab layout area to overflow the window boundaries. The following values are valid: auto: Show scroll bars when necessary. hidden: Do not allow access to overflowing content. scroll: Always show horizontal and vertical scroll bars, even if they are not needed. visible: Content can display outside the bounds of the layout area. Note: In Internet Explorer, layout areas with the visible setting expand to fit the size of the contents, rather than having the contents extend beyond the layout area.
selected	false	A Boolean value specifying whether this tab is initially selected so that its contents appears in the layout.
style		A CSS style specification that controls the appearance of the layout area.

Example

The following example creates a tabbed layout with one tab. When you click the button it creates a second tab that is immediately visible and selected.The main page looks as follows:

<html>
<head>
</head>
<body>
<cfform name="layouts">
<cfinput type="button" name="CreateTab"
onClick="ColdFusion.Layout.createTab('tabLayout','tab2',
'Tab 2','_tabUrl.cfm',{inithide:false,selected:true})"
value="Create Tab">
</cfform>

<cflayout type="tab" name="tabLayout">
<cflayoutarea name="tab1" title="Tab 1" align="left">
Default Tab
</cflayoutarea>
</cflayout>
</body>
</html>

The _tabURL.cfm page looks as follows:

<h3>Tab 2</h3>
