Although the Property inspector enables you to make simple edits to a Collapsible Panel widget, it does not support customized styling tasks. You can alter the CSS for the Collapsible Panel widget and create a collapsible panel that is styled to your liking. For a more advanced list of styling tasks, see www.adobe.com/go/learn_dw_sprycollapsiblepanel_custom.

All CSS rules in the topics below refer to the default rules located in the SpryCollapsiblePanel.css file. Dreamweaver saves the SpryCollapsiblePanel.css file in the SpryAssets folder of your site whenever you create a Spry Collapsible Panel widget. This file also contains useful commented information about various styles that apply to the widget.

TipWhile you can easily edit rules for the Collapsible Panel widget directly in the accompanying CSS file, you can also use the CSS Styles panel to edit the collapsible panel’s CSS. The CSS Styles panel is helpful for locating the CSS classes assigned to different parts of the widget, especially if you use the panel’s Current mode.

You can style the text of a Collapsible Panel widget by setting properties for the entire Collapsible Panel widget container, or by setting properties for the components of the widget individually.

To change the text format of a Collapsible Panel widget, use the following table to locate the appropriate CSS rule, and then add your own text styling properties and values:

Style to change	Relevant CSS rule	Example of properties and values to add or change
Text in the entire collapsible panel	.CollapsiblePanel	font: Arial; font-size:medium;
Text in panel tab only	.CollapsiblePanelTab	font: bold 0.7em sans-serif; (This is the default value.)
Text in content panel only	.CollapsiblePanelContent	font: Arial; font-size:medium;

To change the background colors of different parts of a Collapsible Panel widget, use the following table to locate the appropriate CSS rule, and then add or change background color properties and values to your liking:

Color to change	Relevant CSS rule	Example of property and value to add or change
Background color of panel tab	.CollapsiblePanelTab	background-color: #DDD; (This is the default value.)
Background color of content panel	Background color of content panel	background-color: #DDD;
Background color of tab when panel is open	.CollapsiblePanelOpen .CollapsiblePanelTab	background-color: #EEE; (This is the default value.)
Background color of open panel tab when the mouse pointer moves over it	.CollapsiblePanelTabHover, .CollapsiblePanelOpen .CollapsiblePanelTabHover	background-color: #CCC; (This is the default value.)

By default, the Collapsible Panel widget expands to fill available space. You can constrain the width of a Collapsible Panel widget, however, by setting a width property for the collapsible panel container.

1. Locate the .CollapsiblePanel CSS rule by opening the SpryCollapsible Panel.css file. This rule defines properties for the main container element of the Collapsible Panel widget.
   
   You can also locate the rule by selecting the Collapsible Panel widget, and looking in the CSS Styles panel (Window > CSS Styles). Make sure the panel is set to Current mode.
   
   
2. Add a width property and value to the rule, for example width: 300px;.
