Tag name: <tr:showDetail>
UIComponent class: org.apache.myfaces.trinidad.component.core.layout.CoreShowDetail
Component type: org.apache.myfaces.trinidad.CoreShowDetail
The showDetail provides a means of toggling a group of components between being disclosed or undisclosed. A showDetail should be used to:
- hide/show an entire section or a part of a section of information within the contents of a page such as:
- show more information / hide more information
- show details / hide details
- show "section name" / hide "section name"
- show graph/hide graph, etc.
- hide/show functionality such as:
- simple/advance search
- hide/show details of a table row
On mobile devices the showDetail renders nothing itself, but does renders its children.
If the "prompt" facet is not present, but either the disclosedText or undisclosedText attributes are present (not both), the text in the attribute will appear next to the disclosure icon for both states.
If the "prompt" facet is not present and both the disclosedText and or undisclosedText attributes are present , the text in the disclosedText attribute will appear when disclosed="true" and the text in the undisclosedText attribute will appear when disclosed="false".
Finally, if the "prompt" facet is not present and neither the disclosedText or undisclosedText attributes are present, then the word "hide" will appear next to the disclosure icon when disclosed="true" and the word "show" will appear next to the disclosure icon when disclosed="false". In this case both the "hide" and "show" labels will be links and mnd may be clicked in order to toggle the disclosure.

|org.apache.myfaces.trinidad.event.DisclosureEvent||Apply Request Values,|
|The disclosure event is delivered when a node is disclosed.|
Apply Request Values
|Event delivered to describe an attribute change. Attribute change events are not delivered for any programmatic change to a property. They are only delivered when a renderer changes a property without the application's specific request. An example of an attribute change event might include the width of a column that supported client-side resizing.|
|prompt||Component rendered next to the hide or show icon. If this facet is present, this will be used instead of the disclosedText and undisclosedText attributes.|
|attributeChangeListener||javax.el.MethodExpression||Only EL||a method reference to an attribute change listener. Attribute change events are not delivered for any programmatic change to a property. They are only delivered when a renderer changes a property without the application's specific request. An example of an attribute change events might include the width of a column that supported client-side resizing.|
|binding||org.apache.myfaces.trinidad.component.core.layout.CoreShowDetail||Only EL||an EL reference that will store the component instance on a bean. This can be used to give programmatic access to a component from a backing bean, or to move creation of the component to a backing bean.|
Default Value: false
whether or not to disclose the children
|disclosedText||String||Yes||the text to display when the children are disclosed. If this attribute is set and the undisclosedText attribute is not set, this text will be displayed for both the disclosed state AND the undisclosed state.|
Default Value: false
stops the local value of disclosed from being set by renderers. This allows the value to always be taken from the value of the disclosed value expression. Disclosed values must be updated in other ways (i.e. from a disclosure listener)
|disclosureListener||javax.el.MethodExpression||Only EL||a method reference to a disclosure listener|
the identifier for the component. The identifier
must follow a subset of the syntax allowed in HTML:
Default Value: false
whether data validation - client-side or server-side - should be skipped when events are generated by this component. When immediate is false (the default), the disclosure event will be delivered during the Invoke Application phase, which will trigger validation. When set to true, the disclosure event will be executed during the Apply Request Values phase.
|inlineStyle||String||Yes||the CSS styles to use for this component.|
the IDs of the components that should trigger a partial update.
This component will listen on the trigger components. If one of the trigger components receives an event that will cause it to update in some way, this component will request to be updated too.
Separate multiple triggers with a space. e.g., partialTriggers="cmp1 cmp2"
Identifiers must account for NamingContainers. You can use a single colon to start the search from the root, or use multiple colons to move up through the NamingContainer. For example, "::" will pop out of this component's naming container (it pops out of itself if it is a naming container), ":::" will pop out of two naming containers, etc. The search for the partialTrigger begins from there. e.g., partialTriggers=":::commandButton1" the search begins for the component with id = commandButton1 after popping out of two naming containers relative to this component. To go into naming containers, you separate the naming containers with ':', e.g.,partialTriggers= "nc1:nc2:nc3:componentId".
Default Value: true
whether the component is rendered. When set to false, no output will be delivered for this component (the component will not in any way be rendered, and cannot be made visible on the client). If you want to change a component's rendered attribute from false to true using PPR, set the partialTrigger attribute of its parent component so the parent refreshes and in turn will render this component.
|shortDesc||String||Yes||The short description of the component. This text is commonly used by user agents to display tooltip help text.|
|styleClass||String||Yes||a CSS style class to use for this component.|
|undisclosedText||String||Yes||the text to display when the children are undisclosed. If this attribute is set and the disclosedText attribute is not set, this text will be displayed for both the disclosed state AND the undisclosed state.|
