Jquery ui slider handle vertical offset - jquery-ui

Well this is a very strange issue, for whatever reason slider handle is outside it's parent element by half it's height or width, why did they made it that way?...
Anyways, you can see in this fiddle: http://jsfiddle.net/PGLkW/2/ that handle goes way outside it's container, and if i would try to remove margin like so:
.ui-slider .ui-slider-handle{
width:100%;
margin-left:0px;
left:0px;
margin-bottom:0px;
}
​Things get's even worse, and from what i can see i would actually need to edit widget itself for such a stupid thing, or am i not seeing something?
So just to clarify my question, i want handle to stay within it's container, and when i click on any place to start dragging as you can see mouse doesn't go exactly to the middle of handle, so it looks really bad.

It looks it doesn't read the css properly, or because there are a lot of solutions they left it for the developers to play with it, and you have to do it until you get the result you want, here there is a solution using margin-bottom in negative:
//CSS
.ui-corner-all, .ui-corner-top, .ui-corner-left, .ui-corner-tl{ border-radius: 0; }
.ui-slider .ui-slider-handle{
width: 58px;
height: 50px;
margin-bottom: -25px;
}
//HTML
<div class="slider" style="margin:50px; height:400px; width:50px;"></div>​
The fiddle http://jsfiddle.net/RFVZ2/ . I hope this works for you.

The solution is described in this bug report ("this is as designed"): http://bugs.jqueryui.com/ticket/4308
For horizontal slider I used:
.ui-slider-handle
{
height: 24px !important;
margin-bottom: -6px !important;
}

A full page layout with resizable panes using jQuery UI

I'm trying to create the overall layout of a webapp. The app is full-screen and has a fixed header and three columns/panes. The center pane consists of two rows:
The panes should be resizable through dragging the pane edges with the mouse (see arrows in image above).
The individual panes have should have vertical scrollbars in case of overflowing content, that is, no global browser window scrollbar.
Using jQuery and jQuery UI Resizable, I've created this (partly working) JSFiddle.
HTML:
<div class="header">
Fixed header
</div>
<div class="wrapper">
<div class="inner-wrapper">
<div class="left pane">Left</div>
<div class="center pane">
<div class="inner">
<div class="top">Center top</div>
<div class="bottom">Center bottom</div>
</div>
</div>
<div class="right pane">Right</div>
</div>
</div>
CSS:
html, body {
height: 100%;
}
.header {
position: fixed;
top: 0;
left: 0;
right: 0;
height: 20px;
background-color: moccasin;
}
.wrapper {
position:absolute;
top: 21px;
right: 0;
bottom: 0;
left: 0;
background-color: fuchsia;
}
.inner-wrapper,
.center.pane .inner {
display: table;
width: 100%;
height: 100%;
}
.pane {
display: table-cell;
}
.left.pane {
background-color: olivedrab;
}
.center.pane {
background-color: lightblue;
}
.center.pane .inner .top,
.center.pane .inner .bottom{
display: table-row;
}
.center.pane .inner .top {
background-color: lightcoral;
}
.center.pane .inner .bottom {
background-color: orange;
height: 100%;
width: 100%;
}
.right.pane {
background-color: #999;
}
JavaScript:
$(function () {
$(".left.pane").resizable({
handles: "e, w"
});
$(".right.pane").resizable({
handles: "e, w"
});
$(".center.pane .inner .bottom").resizable({
handles: "n, s"
});
});
It has several issues, including:
When resizing Left, Right is also resized (which it shouldn't)
When resizing Left towards full width, Center content is hidden under Right
When resizing Right the wrapper (Fuchsia-colored) is partly visible
Center bottom is resized through the top of the Center top, not through it's own top
I'm aware of the jQuery Layout plugin, but as far as I can see, it doesn't offer quite the layout I'm after. Also, I want to keep it as simple as possible.
Furthermore, I have tried Methvins splitter plugin, but couldn't get it to work.
My question:
Any suggestions for how to create a layout as in the image from jQuery UI Resizable and what I have in the JSFiddle?
There are more appropriate plugins, based on jQuery to obtain what you want.
OPTION 1:
I personally used in a my project UI Layout.
It is an almost old project (6 years ago), but in mid-2014 its development is re-started, even if there are no more information after september 2014.
Actually, last stable version is 1.4.3, released in sept '14. New website is:
https://github.com/allpro/layout/
OPTION 2:
If you need a more complete solution, you could think about jEasy UI, that is a complete framework that
[...] helps you build your web pages easily
It is a sort of replacement of jQuery UI, with some similar widgets (dialogs, accordions, ...) and something exclusive, like Layout module, already linked in my answer.
OPTION 3:
Analogue solution to the previous one, is Zino UI, another complete UI framework that has a specific component dedicated to "Split Layout"
OPTION 4:
jQWidgets is another library, with similar purposes of previous ones, and specifically could be interesting jqxSplitter module.
Related alternative (similar):
There is also another alternative, that allows to slice panels in the browser windows but in addition allows to drag&drop single panels creating different tabs, and side-by-side sub-windows.
This is called Golden Layout. It's different from previous ones, for many reasons also more powerful but surely at the moment it has not Touch support...
There were a few small problems that caused the behaviour that you don't like.
These were fixed in this Fiddle
The problems were:
When resizing Left, Right is also resized (which it shouldn't)
Fixed by setting a initial width (in percent)
When resizing Left towards full width, Center content is hidden under Right
Couldn't reproduce
When resizing Right the wrapper (Fuchsia-colored) is partly
visible Center bottom is resized through the top of the Center top,
not through it's own top
Fixed by setting left to 0 during resize.
$(".right.pane").resizable({
handles: "e, w",
resize: function(event, ui) {
ui.position.left = 0;
}
});
Center bottom is resized through the top of the Center top, not through it's own top
This is due to that JQuery UI Resizable uses relative positioning which do not work in table cells. Fixed by adding a content div that handles the resize.
<div class="top pane">
<div class="top-content">Center top</div>
</div>
I found one which seems acceptable for this requirement, if you looking for something more minimalistic compared to jEasy UI. : )
http://w2ui.com/web/demo/layout
Also it's no dead project; Seems still active on github https://github.com/vitmalina/w2ui/, which is nice.
I'll give it a try. Just wanted to share this, to save others search time, hopefully.
i'm usign this plugin
with jquery
http://www.bramstein.com/projects/jlayout/jquery-plugin.html
I came up with the answer to this myself, although in the end it took me over a year of development! The result is a modern, responsive panel layout widget built using jQuery and jQuery UI widget factory.
http://www.silvercore.co.uk/widgets/propanellayout/
The best solution at the time the question was asked was undoubtedly jQuery UI.Layout, but over time that project has stagnated and the plugin does not work with jQuery 2. Despite the code being released on GitHub its fate is unknown, which makes using it as the foundation of a long term project questionable.
A few of the other links posted here are dead now and if you don't want or need a full application framework your choices are limited.
OK, hopefully my last edit. Went through a bunch of these, and ended up with jQuery UI layout.
Goldenlayout is nice, but you have to actually add the html in each pane through javascript. If you've got all your stuff in react components I guess this might be fine, but not for my use case.
jQuery UI layout seems to be pretty robust and was just updated in 2014.
You can use Gridstack
It's easy to use and powerful.

jQuery UI selectable and scrollbar

I have a div with divs inside. The outer one has overflow-y: auto;, so with many internal items the right scrollbar appears. After doing $('#container').selectable(); when I press left mouse button over the scrollbar, it doesn't scroll, but a dotted frame for selecting is shown.
I have found this solution: JQuery UI Selectable plugin: Make scroll bar not selectable when div overflows
Unfortunately, it doesn't work for me, because when I scroll to the bottom, the items stop being selectable. (Though the top ones continue). So, the question is: how make the scrollbar... mmm... a scrolling bar, without splitting the container into 2 divs.
Well, it seems to be all browsers problem: when you click on a scrollbar, a mouse event is fired. This is the real problem, jQuery UI just doesn't solve it. Let's fix it on our own in the jQuery UI .js file (not applied to the min version as it should be obfuscated AFAIK).
Add this condition
if (event.pageX > $(event.target)[0].clientWidth + $(event.target).offset().left)
return;
right after the
_mouseDown: function(event) {
I have seen a lot of such hacks with HasScrollbar() detectors, but don't get why didn't they just sum up client width (that is without scrollbar) and offset to make it relative to the document and compare with pageX. For me it works perfectly.
Use a wrapper div for this , Its working fine for me.
.selectable-wrapper { border-radius: 5px; min-height: 200px; max-height: 200px; overflow-y: auto; border: 1px solid #D1D1D1;}
.selectable { list-style-type: none;padding: 5px;}
<div class="selectable-wrapper">
<ul class="selectable">
</ul>
</div>

jQuery UI Autocomplete Width issue

please see this http://jsfiddle.[net]/Nkkzg/108/ (SO doesn't allow to like to JsFiddle) and write 'Apple' in auto-complete text box. You can see a long string appears and with that page's horizontal scroll bar also appear which is very annoying.
I want to show the full string as a result without setting the width, You can see autocomplete results div shows from the left corner to maximum right depending on string length. How can we show the results in the center of page like input textbox, so that horizontal scroll bar shouldn't appear.
Any help will be highly appreciated.
Thanks and Regards.
According to this article:
jQuery UI Autocomplete Width Not Set Correctly
It looks as though you need to place everything in a container and specify the appendTo property telling it where to put the menu.
You should try to use position:absolute
.ui-autocomplete {
max-height: 200px;
overflow-y: auto;
/* prevent horizontal scrollbar */
overflow-x: hidden;
border:1px solid #222;
position:absolute;
}
Live Demo
You could try to put this in your .css file
span input.ui-autocomplete-input {
width: 100%;
}
In that way the autocomplete get's the width you have style it to according to the styleClass that is on the enclosing span tag

How to center field_with_errors class

I've recently installed Devise, and I've got the sign-in form working as it should, displaying errors etc...
However, the sign-up form is acting very strange i.e when displaying errors they appear on the left side out of proportion with the rest of the app. Here is a screen shot to illustrate: http://i.imgur.com/1r4hQMM.png note: this only happens when there are errors, it is centered otherwise.
Now i've tried editing the field_with_errors CSS with the following:
.field_with_errors {
display: block;
clear: both;
text-align: center; }
And still, it remains on the left hand side. I have noticed that float: right; seems to move it to the right, but how can I get it in the center with the rest of the form?
field_with_errors seems pretty darn stubborn in CSS.
If you want to center text then text-align: center will work, but in this case you wish to center an entire element and should therefore use margin: auto auto instead.
Enjoy!
you can also use flexbox
.my class {
display: flex;
align-items: center;
justify-content: center;

jQuery autocomplete list position change

I would like to move position a bit to the left of my jQuery UI suggestion list. Here function and everything work very fine
Unfortunately I have no idea how to move that list a bit to left align left about 10px the page is responsive that is why scared that how to move left.
I think this is the documentation: http://docs.jquery.com/Plugins/Autocomplete/autocomplete.
You can set the style in this class
.ui-menu .ui-menu-item a.ui-state-hover, .ui-menu .ui-menu-item a.ui-state-active
{
margin-left: -10px !important;
}
Try adding this in your CSS and not in the jQuery-ui CSS file
you can add margin-left: -11px; in to the list DIV
