Open and close the Sidebar in EJ2 JavaScript Sidebar control

28 Jan 20259 minutes to read

Opening and closing the Sidebar can be achieved using built-in public methods.

  • show(): Method to open the Sidebar.
  • hide(): Method to close the Sidebar.
  • toggle(): Method to toggle between open and close states of the Sidebar.

In the following sample, the toggle method is used to show or hide the Sidebar on a button click.

ej.base.enableRipple(true);

//Sidebar initialization
var defaultSidebar= new ej.navigations.Sidebar({
    showBackdrop: false,
    open:function(e)
    {
        console.log("Sidebar is opened");
    },
    close: function(e)
    {
       console.log("Sidebar is closed");
    }
});
defaultSidebar.appendTo('#default');
//end of Sidebar initialization

// Open the Sidebar
document.querySelector('#open').addEventListener('click', () => {
    defaultSidebar.show();
})

// Toggle(Open/Close) the Sidebar
document.getElementById('toggle').onclick = function() {
    defaultSidebar.toggle();
};

// Close the Sidebar
document.getElementById('close').onclick = function() {
    defaultSidebar.hide();
};
