Introduction

A TitlePane is a pane that can be opened or collapsed, with a title on top. The visibility of the pane’s contents is toggled by activating an arrow “button” on the title bar via the mouse or keyboard. It extends ContentPane but since it isn’t used inside other layout widgets it’s not in the dijit.layout module.

Usage

The constructor for TitlePane takes the following possible parameters in its keyword arguments:

Parameter	Type	Description
title	String	The title to be displayed in the pane header. The default is an empty string.
content	DomNode | NodeList | dijit._Widget	The content (innerHTML) to be displayed in the pane.
open	Boolean	Boolean option whether or not to display the pane contents. The default is true.

Examples

Programmatic example

<script type="text/javascript">
  dojo.require("dijit.TitlePane");

  var tp;
  dojo.addOnLoad(function(){
      tp = new dijit.TitlePane({title:"I'm a TitlePane", content: "Collapse me!"});
      dojo.byId("holder").appendChild(tp.domNode);
  });
</script>

<script type="text/javascript"> dojo.require("dijit.TitlePane"); var tp; dojo.addOnLoad(function(){ tp = new dijit.TitlePane({title:"I'm a TitlePane", content: "Collapse me!"}); dojo.byId("holder").appendChild(tp.domNode); }); </script>

<div id="holder"></div>

<div id="holder"></div>

Declarative markup

Creation from markup is even easier.

<script type="text/javascript">
  dojo.require("dijit.TitlePane");
</script>

<script type="text/javascript"> dojo.require("dijit.TitlePane"); </script>

<div id="tp2" dojoType="dijit.TitlePane" title="I'm a TitlePane Too">
    Click arrow to close me.
</div>

<div id="tp2" dojoType="dijit.TitlePane" title="I'm a TitlePane Too"> Click arrow to close me. </div>

AccordionContainer substitute

Sometimes when developers think they want an AccordionContainer what they really want is a set of TitlePanes. With a set of TitlePanes the outer div doesn’t have any fixed height, and you can open multiple panes at once (or close all of them).

For example:

<script type="text/javascript">
  dojo.require("dijit.TitlePane");
</script>

<script type="text/javascript"> dojo.require("dijit.TitlePane"); </script>

<div style="border: solid black 1px;">
  <div dojoType="dijit.TitlePane" title="Pane #1">
    I'm pane #1
  </div>
  <div dojoType="dijit.TitlePane" title="Pane #2">
    I'm pane #2
  </div>
  <div dojoType="dijit.TitlePane" title="Pane #3">
    I'm pane #3
  </div>
</div>

<div style="border: solid black 1px;"> <div dojoType="dijit.TitlePane" title="Pane #1"> I'm pane #1 </div> <div dojoType="dijit.TitlePane" title="Pane #2"> I'm pane #2 </div> <div dojoType="dijit.TitlePane" title="Pane #3"> I'm pane #3 </div> </div>

Screen Reader Information

The title pane container will have an ARIA labelledby property which points to the id of the title pane title. The title pane title has the ARIA role of button and property of haspopup=true to indicate that it controls the display of the pane. The role of button is used to indicate to the user that an action will occur when the button is activated. The tilte pane container will have an ARIA role of region which will be supported in Firefox 3 and identified by future versions of the screen readers.
