Let's dive in and take a look at some of the widgets that jQuery UI provides for us to use in our web applications. So, I am going to scroll down, and I'll start off by looking at the Accordion widget. Now, before I go into the demo for this particular widget, I want to point out how the demo pages are laid out here on jqueryui.com. So, right here in the middle is the widget that's being demonstrated, and then over here on the right-hand side there are various options you can set for that particular widget, under the Examples section.
If we scroll down a little bit more, you can see that there is a view source option, and if I click on view source, then the source code that was used to build this particular example right here is listed out. When you download jQuery UI, all of the source code for the demos comes down with the download anyway. So, you can either choose to use that sample code or you can copy and paste from here on the website. All right! Let me go ahead and close the view source. Last thing I want to point out is the API documentation. Each one of the widgets has a link to the API documentation for that widget.
So you can see here that this is the page that explains all the various things that the Accordion widget can do, explains in detail all the different options, how to call it with various different properties, and so on. All right! So let's scroll back up, and let's go back to the Demo. So, Accordion widgets, I'm sure you have seen these before, they are used to break up information into easily expandable sections, right? So, I click on each section and then it gets slowly revealed into place. But of course there are various options I can use. For example I can customize the icons.
I can have the Accordion widget open just by hovering instead of clicking, and so on, and so forth. We'll actually use the Accordion widget a little bit later when we build our real site. One of the things I want to point out really quickly though, is that to use many of these widgets is really pretty simple. Let's go down to the view source, and you can see here that just to use the Accordion widget, all you need to do is call the accordion function and pass in whatever parameters you want to use on the ID of the element that you want to be the accordion.
If we go down to the source code a little bit further, you'll see that here's the div with the ID of the accordion on it, and it follows some internal structure, right? These h3s provide the titles. These divs provide the content, and so on. But all you have to do is set up your content like you normally would anyway and then just call the accordion function and off it goes. So, next is the Autocomplete widget. Autocomplete allows me to have a text field. When I type certain letters, you can see that I'm getting a whole bunch of predefined options that have that letter in it.
So, let's check off the A and type a J instead. You can see that I'm getting programming languages that just have the letter J in them. And I can get more specific if I start doing things like this. And once again, the Autocomplete box has a whole bunch of different options over here on the right-hand side. I can have it show up as a Combo box. I can have various categories. So if I type a little a again, you can see that there is Categories in here that you can't select. A pretty rich set of functionality for an Autocomplete wwidget.
jQuery UI also provides buttons. Now here are the pretty standard simple buttons, but you can of course have things like checkboxes. Here they are, behaving like checkboxes. You can assign icons to your buttons. You can have them behave like Radio button. You can have a Split button, which has various different actions here. You can build toolbars out of buttons, pretty rich functionality. Than there is a Datepicker widget. I am sure you have seen these before. It allows you to choose a date. All right, pretty straightforward, you can have multiple dates.
Here is Display multiple months, right here. So you can imagine if you are checking into a hotel or choosing plane flights and so on, this would be very useful. You can even have them be localized. So if I choose Localization, you can see that here's the Calendar in French. We can also use various different writing formats. You know, here's one in a right-to-left languages, using Hebrew. Okay, let's move on. Here's the Dialog widget. I am sure you have seen dialogs before, nothing really earth shattering here. But there's a Basic dialog. There is Modal dialogs, and then you can have Modal messages and so on.
These are pretty useful in modern web apps. There is a new Menu element here in jQuery UI. Now they are still working on the Menu bar as of this recording, but this is the Menu element, and you can see, you can customize it with icons. Here is the Progressbar. Progressbar of course, we've all seen these before. You can have them with various labels and indeterminate value and so on. This is the Slider control, again very useful control. Here is one with multiple sliders, all right. Here's a Range slider.
You can see that this is pretty useful. You can imagine like you know choosing a range of hotel room prices you want to pay. Down here is the Spinner control. The spinner control is pretty straightforward. It just allows you to use these up and down arrows to quickly choose numbers. There is the Tabs control. Again, I'm sure we've all seen tabs before. And there's the Tooltip control. So that's a pretty brief recap of the widgets available in jQuery UI. So, let's move on to our next section.
