Basic Collapsible with Bootstrap

Basic Collapsible

• Collapsibles are useful when you want to hide and show large amount of content:

Add bootstrap Library to your WordPress Functions.php

function my_js_scripts() {
/**
*	Use latest jQuery and bootstrap Libs 
*/
if( !is_admin() ){
	wp_deregister_script('jQuery');
	wp_deregister_script('bootstray');
	wp_deregister_script('localLib');
	
	wp_register_script('jQuery', "https://ajax.googleapis.com/ajax/libs/jquery/3.3.1/jquery.min.js"); 
	wp_enqueue_script('jQuery');
	wp_register_script('bootstrab', "https://maxcdn.bootstrapcdn.com/bootstrap/3.3.7/js/bootstrap.min.js"); 
	wp_enqueue_script('bootstrab');
		/* local Lib depends heavily on Jquery - 3rd. param */
	wp_enqueue_script('localLib',  get_stylesheet_directory_uri().'/scripts/myJSLib.js', array('jquery'),'0.9', false );
	wp_enqueue_script('localLib');
	}
}
  
function my_css_style() {
 /* wp_enqueue_style( 'style-name', get_stylesheet_uri() );  //This is for getting style.css of current theme	*/
   wp_register_style( 'cssStyles', get_template_directory_uri() .'css/genericCSS.css');
   wp_enqueue_style( 'cssStyles' );
   wp_register_style( 'bootstrapStyles', 'https://maxcdn.bootstrapcdn.com/bootstrap/3.3.7/css/bootstrap.min.css');
   wp_enqueue_style( 'bootstrapStyles' );
} 	

add_action( 'wp_enqueue_scripts', 'my_js_scripts' );
add_action( 'wp_enqueue_scripts', 'my_css_style' );
