I'm creating a contact form, which I want to be pop out (and greyed) and wanted to know if fancybox could be used for this purpose. I currently use it for images but curious to see if it could work for this purpose.
You can use fancy box for a form.
You might have to make some changes to the plugin to get it work though
you can see how to do it here
Based on your comment: There are a few ways to get that done:-)
One way, is to have multiple divs within the form. Make the next button hide one div and show another in the modal. This can be done as many times as you need to do it within the same modal. Then when the form is complete, you can have a submit button now instead of a next or previous button.

I'm building an app to manage some users, where i have a page to list them. On each user i have some buttons to make some actions on them, like edit them or delete them.
When the delete button is pressed, i would like to have a modal to show up and ask if you really wawnt to delete the user. As i may be using this modal in other places, i thought i should make it kind of generic to receive the different messages i want to show, so i built a component for it.
I've searched through some examples, but i couldn't find one similar to mine.
I've made the template for the modal and the component to back it up, but i don't know how to show it, for example, on a button click.
Any help is appretiated :)
Thanks
EDIT: i'm trying to use bootstrap modals
use bootbox instead of making a modal from scratch. they can be perfectly used for delete confirm or alerts. I use them. http://bootboxjs.com/. It is also available for angularjs.
I'm working something like a dynamic menu, where you click some radio buttons and it shows a specific form, each radio control matches to a different form.
Examples from the showcase always base themselves on the Tabs widget and I don't need that behaviour.
I opted for placing all the forms inside one Canvas and hide/show them accordingly (Not sure this was the best idea, if someone knows better I would like to hear it)
Now my problem is that every onClick event has to .show() one form and .hide() the other 9. that is annoying.
Is there a way to "get" the current displayed child in the Canvas and hide it?
If what you want is basically mutex display, you could put all the components as members of a Layout instead of a Canvas, then use setVisibleMember(). That hides all other members.
When to use HyperLink and when to use Anchor?
When using HyperLink how to handle clicks?
com.google.gwt.user.client.ui.Hyperlink.addClickHandler(ClickHandler) is deprecated
com.google.gwt.user.client.ui.Hyperlink.addClickListener(ClickListener) is deprecated as well.
Doc suggests to use Anchor#addClickHandler, but how to use Anchor#addClickHandler when using HyperLink
Does it mean that if I need to handle click I should always use Anchor and never use HyperLink?
Great question, because it is so simple, and yet opens up what might be a whole new area for a lot of GWT programmers. I've up-voted the question just because it can be a great lead-in for people exploring what GWT can do.
Anchor is a widget for storing and displaying a hyperlink -- essentially the <a> tag. Really not much more exciting than that. If you want your page to link to some external site, use anchor.
Links are also used for internal navigation. Let's say I have a GWT app that requires the user to login, so on my first panel I put a login button. When the user clicks it, I would display a new panel with widgets to collect the user's information, code to validate it, and then if validated successfully, reconstruct that first panel the user was on.
Buttons are nice, but this is a browser, and I want my user's experience to be more like a web page, not a desktop app, so I want to use links instead of buttons. Hyperlink does that. The documentation for hyperlink describes it well:
A widget that serves as an "internal" hyperlink. That is, it is a link
to another state of the running application. When clicked, it will
create a new history frame using History.newItem(java.lang.String),
but without reloading the page.
Being a true hyperlink, it is also possible for the user to
"right-click, open link in new window", which will cause the
application to be loaded in a new window at the state specified by the
hyperlink.
That second sentence should help clear it up. The hyperlink is not changing the page in a URL sense (the way anchor does), though the URL will reflect the state of the program by displaying the "token" associated with the hyperlink appended to the base URL after a slash. You define the token. It would be something descriptive like "login" or "help" or "about". But this isn't a new page. There is no additional HTML file you've had to construct to display a help page, for example. It is the state of the current GWT app that is changing. Even if you "open in a new window" you are just running the same app in a particular state.
It looks like a link, but it is really a widget that manipulates the history frame, which in turn allows you to move the state of your GWT application. You don't write a click handler for the hyperlink widget, but a value change handler for the history stack. When you see that the "help" token has been put on the history stack, your handler will execute GWT code to attach to the RootPanel a FlowPanel with embedded HTML text with your help information. This is perceived by the user as a "new page", which is what he expects when he clicks on a hyperlink. The URL will be something.html/help. Now pretend he returns to this URL via the back button, not your hyperlink. No problem. You don't care about the hyperlink click. You only care that, somehow, the history stack changes. Your value change handler fires again, and does the same thing as before to display the help panel. The user still enjoys the experience of navigating through web pages, even though you and I know that there is only one web page and that you are attaching and detaching panels to the RootPanel (or whatever scheme you are using to display your GWT panels).
And this leads to a bonus topic.
This bonus is a bit more complicated, but ironically, it could help better understand hyperlinks. I say more complicated, but really, it helps solidify this notion that a GWT application is made up of a series of states, and that the web page on the screen is just the user's perception of those state changes. And that is Activities and Places. Activities and Places abstracts away this history frame manipulation, handling it in the background once you've set up a mapper with a GWT-provided class designed for this purpose, allowing you to break down your app into a series of activities, and as the user interacts through these activities he is put into different places, and each place has a view. Moreover, the user can move from place to place using browser controls like the address bar, bookmarks, history, and the backward/forward buttons, giving the user a real web-like experience. If you really want to get a grip on the conceptual difference between hyperlinks and anchors, you should try to learn this GWT topic. It can really make you change the way you see your apps, and for the better.
Hyperlink (or InlineHyperlink) is basically no more than a kind of Anchor with a ClickHandler that calls History.newItem and preventDefault() the event (so that the link is not actually followed).
Actually, Hyperlink won't do that if it thinks (and yes, it's only a guess) you right-clicked or middle-clicked (or ctrl-clicked) on the link (depending on the browser), to open the link in a new window or tab.
If you need any other behavior, then don't use Hyperlink and use Anchor instead. And if you want to add some behavior to an Hyperlink, then use an Anchor and mimic what the Hyperlink does. And you can reuse the HyperlinkImpl to have the right-click/ctrl-click handling (see links below).
But actually, if you need something that looks like a link and do something on click, but does not have a "target URL" (i.e. it shouldn't be right-clicked/ctrl-clicked to open in a new window/tab, or it wouldn't mean anything to do so), then do not use either an ANchor or Hyperlink, use a Label of whatever instead, and make it look like a link (but well, maybe you should use a Button and have it look like a button then; Google used to have link-alike buttons –such as the "refresh" link/button in GMail– and changed them to look like buttons when they really aren't links).

I am trying to find the most usable/accessible way to implement a simple form dropdown list which will sort a list of products by pice and alphabetical order.
In your opinion is the dropdown more usable when there is a button that governs its submission or when it automatically submits onchange of the dropdown?
The research I have read is both for and against such methods and there is a variery of implementations on the web so interest to hear the thoughts of the community.
Thanks in advance
As a blind computer user either method works fine. I find that having a button to click is slightly easier for me then the onchange event firing. I wouldn't say it's a big enough difference to take into account though assuming the majority of your users will not be disabled. If your targeting specifically blind users I would not use the onchange event.
So long as you do not change focus or navigate to another page when the selection changes, either approach should work. The classic example of a problem dropdown is where it contains a list of other pages on the site, and navigates as soon as the selection changes. This prevents a keyboard user from using the list; they can't browse it, and can't navigate to any pages beyond the first selection, since it's impossible to navigate past those. So in cases where focus changes or the page navigates as a consequence, having a separate action (eg. Go button, or handling enter) to cause the navigation to take place is essential. This is likely where the advice you've read is coming from.
In this case, however, it sounds as though you are just updating content elsewhere on the page, and not changing focus or doing navigation. Simply resorting existing content should be fine.
Depends on your users and their respective expectations and the context in which it's presented.
As a blanket, general statement, you should have the drop down accompanied by very obvious submission button. That is the safer approach.
If you are refreshing page data or if the focus moves away after the dropdown option is selected, you should use a button to be accessible. If you fire the event on change, blind or keyboard-only users will not be able to use the dropdown menu at all if they are on windows with ie and chrome (so added together, a majority of the people on windows). As soon as they use the arrows to scroll down and make a selection, the first option they hit will be selected and the page data will refresh or the focus will move, making it impossible for them to navigate or select the second option, third option, etc. Below is a thorough explanation with examples so you can see what I mean.
Designers definitely don't like the buttons, but if you are blind and on chrome/ie, it is impossible to use a lot of dropdowns without it. I'm guessing Jared uses firefox or a mac.

In Drupal, how do you get the submit button to appear last on a create content form without making the entire form from scratch? I can set the weight of the submit button using code, but it never goes below any custom fields I've created. If I drag a lot of custom fields from the bottom of the form to the top, the submit button only stays below about 5 of the fields and then all the other fields get stacked below it. It feels like the submit button is simply stuck in one position on the screen. How do I fix that?
In a hook_form_alter():
$form['submitbuttonid']['#weight'] = 100;
But it seems like something is getting in the way. Typically in Drupal the Submit is always last unless something funny is going on.
Okay, I had just upgraded to the latest version of views and cck. I reverted back to the versions just before that and now the submit button has returned to the bottom of the form. (And a few other niggling errors I never used to have went away)
