collapse or expand p:accordionPanel programmatically

What I am trying to achieve is?

I have gone through accordion panel primefaces documentation but could not found it helpful. http://www.primefaces.org/docs/vdl/3.5/primefaces-p/accordionPanel.html

I have gone through previously asked question on stackoverflow, the answer to this question also could not satisfy me to achieve my required result.

Expanding Accordion Panel in PrimeFaces with a RadioButton click

ManagedBean


    package com.pk.test;

    import javax.faces.bean.ManagedBean;

    @ManagedBean(name="testBean")
    public class AccordionTestBean {

        private String name;

        private String semester;

        private String age;

        private Boolean checkNameTextField = false;

        public void save(){
            System.out.println("Close Filter If any one field of form is set");
            System.out.println("Name: "+getName());
            System.out.println("Age: "+getAge());
            System.out.println("Semester: "+getSemester());
            if(getName()!= null){
                setCheckNameTextField(true);
    //if name textfield is set to a value, on save click filter will not collapse or close
            }
            else
                setCheckNameTextField(false);
    //if name textfield is set to a value, on save click filter will collapse

        }

        public String getName() {
            return name;
        }

        public void setName(String name) {
            this.name = name;
        }

        public String getSemester() {
            return semester;
        }

        public void setSemester(String semester) {
            this.semester = semester;
        }

        public String getAge() {
            return age;
        }

        public void setAge(String age) {
            this.age = age;
        }

        public Boolean getCheckNameTextField() {
            return checkNameTextField;
        }

        public void setCheckNameTextField(Boolean checkNameTextField) {
            this.checkNameTextField = checkNameTextField;
        }
    }

I did'n understand what you are trying to do, but to expand/colapse an accordion panel you can use this

expand: PF('accordian-widgetVar').select(index)

collapse: PF('accordian-widgetVar').unselect(index)

where accordian-widgetVar is the value of the property widgetVar of your accordionPanel and index is the index of the tab that you want to expand/collapse

also you can execute that from a bean like this RequestContext.getCurrentInstance().execute("PF('accordian-widgetVar').unselect(index)");
