Explanation / Answer
1) The Accordion widget lets the user display the contents of a panel by clicking on the header of the panel.
· Each container has a heading element associated with it that is used to open the container and display the content. When you click on a heading, its content will slide into view with an animation also below it. The currently visible content is hidden, while the new content is shown whenever we click on an accordion heading.
· The accordion widget is a robust and highly configurable widget that allows you to save space on your web pages, by displaying only a single panel of content at any time.
· The height of the accordion's container element will be set automatically, so that there is room to show the tallest content panel in addition to the headers. Also, by default, the size of the widget will remain fixed, so that it won't push other elements on the page around it out of the way, when content panels open or close.
Note: Only one content panel can be open at a time when using Accordion Widget.
2) To use a plugin you must code the script element of the jquery library.
The jQuery library is a single JavaScript file, and you reference it with the HTML <script> tag (notice that the <script> tag should be inside the <head> section):
<head>
<script src="jquery-3.2.1.min.js"></script>
</head>
Script is a flow element that executes a script program specified by the user to process, produce or consume jobs.A script flow element can be a processor, producer or consumer depending on the specifications in the attached script declaration. In addition, the script declaration may inject extra properties into the script element and into its outgoing connections. These extra properties serve as arguments to the script program. A script package is an archive file (with filename extension "sscript") that contains all information about a script. It includes a script declaration, a script program, and possibly an icon to be displayed in the Switch flow designer instead of the standard script element icon. A script package can be exchanged between users as a single entity.
3) Datepicker widget is associated with a text box. A Text box is an editable control suitable for character, numeric, and date/time data details. In other words, the datepicker widget is tied to a standard form input field.
The source for datepicker can be as follows:
a) For Pop-Up datepicker:
<input type="text" data-role="date">
b) For inline datepicker:
<input type="text" data-role="date" data-inline="true">
4) Before you can use most plugins for jquery, you must download them and store them on your web server for further use.
Compressed and uncompressed copies of jQuery files are available. The uncompressed file is best used during development or debugging; the compressed file saves bandwidth and improves performance in production. You can also download a sourcemap file for use when debugging with a compressed file. The map file is not required for users to run jQuery, it just improves the developer's debugger experience. Without downloading the jquery library, you can not use them with your code to get the functionality of jquery.
The following steps can be followed
1) Download Jquery from available sources
2) Copy the js file into your root web directory
3) In your index.php or index.html between the head tags include the following code, and then JQuery will be installed:
