Expand All or Collapse All for the Tree

[chong2000]

Hi,

I would like to have commandLink function with Expand All or Collapse All for a tree in richfaces.

Wonder anyone has hints or idea to do that?

Thanks.

You can expand/collapse node from code, see

UI Code:

<h:commandButton value="Collapse All" action="#{sampleBean.collapseAll}"/>

<h:commandButton value="Expand All" action="#{sampleBean.expandAll}"/>

sampleBean
----------------
public UITree treeBindingVariable; // bind this variable to the tree

public void expandAll()
{
treeBindingVariable.queueExpandAll();
}



public void collapseAll()
{
treeBindingVariable.queueCollapseAll();
}
