I am using Element's Notification component but when it is activated the dialog appears but seems to be "behind" the grey background that is also introduced. Clicking anywhere removes the grey background and allows the interaction with the dialog box but without the greyed out background that should be filtering out the noise of the normal screen. Here is a short video that shows the various states:

The code to put the component in as follows:
<div class="add-address" #click="showAddDialog = true">
+
</div>
</div>
<el-dialog
title="Add New Address"
:visible.sync="showAddDialog"
width="30%"
:before-close="newAddressDialogClosed">
<span>Postal Address</span>
<el-input v-model="newAddress" type="text"></el-input>
<span slot="footer" class="dialog-footer">
<el-button #click="dialogVisible = false">Cancel</el-button>
<el-button type="primary" #click="dialogVisible = false">Confirm</el-button>
</span>
</el-dialog>
I have used the inspector to poke around at the CSS but I haven't yet understood what's causing this from a CSS perspective nor a Vue/Element perspective. Any help would be appreciated.
I have further analyzed the HTML/CSS and the component appears to introduce two separate blocks in the DOM:
The lower block is the grey background which you'd expect to "blur" the page and focus attention on the modal. It, however, is in front of the dialog. Also of interest is that clicking anywhere seems to target the grey background and dismiss it but in so doing it also has a subtle effect on the placement on the dialog box as can be seen here:
Note that the z-index of the dialog box is greater than the background which intuitively makes sense to me but I'd have thought this would have put the dialog box on top. Guess that's not all there is to this.
I have hacked a work-around for now by changing the background to display: none and then adding the following HTML directly before the modal dialog in the DOM:
<div class="modal-background" v-if="showAddDialog"></div>
These seems to validate my underlying suspicion that placement within the DOM tree is important and the component's attempt to place the modal background at the very end of the DOM is somehow problematic.
I had the same issue and also found changing the z-index of the dialog had no effect. This was occurring when I had nested Element.Eleme.io elements, which appears to be the case for you also.
The z-index is not quite as simple as "higher always means on top". Elements are grouped into different stacking contexts; it is not possible for an element in a lower stacking context to appear above an element in a higher stacking context. Therefore depending on where the different elements were rendered in the DOM, they can land themselves in different stacking contexts, and are destined to remain at the same relation to one another, no matter how much the z-index has changed. (See https://philipwalton.com/articles/what-no-one-told-you-about-z-index/ for a more detailed explanation on the z-index).
Examining with Chrome dev tools, I found that the obscuring modal is not rendered in the same place as the dialog; in fact it is appended to the body, i.e. on the outer reaches of the application, which appears to be the reason they are not within the same stacking context. There is a quick fix; the dialog element has a property "modalAppendToBody". If true, the modal is rendered to the body, and if false it is rendered to the parent element of the dialog. By specifying this as false I managed to solve the issue:
<el-dialog
title="Add New Address"
:visible.sync="showAddDialog"
width="30%"
:before-close="newAddressDialogClosed
:modalAppendToBody="false">
</el-dialog>
you can use the CSS property called z-index
either any object which you want to set to back ? you just have to set z-index: -1; // or more
or you want to set any object on to the front of another ? you just have to set z-index: 1; //or more
Check the Snipet For More Info :
.a {
position: absolute;
left: 0px;
top: 0px;
z-index: -1;
}
.b {
margin-top:150px;
position: absolute;
left: 0px;
top: 0px;
z-index: 1;
}

Is it possible to have Reveal JS only display the control arrows on the speaker view?
Setting controls: false disables the arrows on both the main display, and the speaker display. My presentation is in front of a live audience, so they don't need to see the controls, but it'd be handy for me to be able to see them, so I know when I've got slides "below" the current one, as well as "to the right" of it.
Assuming that your presentation is loaded as the main page (not in an iframe) adding the following to your presentation should work.
<style>
.reveal .controls {
visibility: hidden;
}
.notes .reveal .controls {
visibility: visible;
}
</style>
<script>
if (window.self !== window.top) {
document.body.className += " notes";
}
</script>
This adds a notes class to the body when the presentation is loaded within an iframe (as is done with the notes plugin). The styling then hides the controls unless it's on the speaker notes page.
If you add it before the call to Reveal.initialize() you shouldn't see the controls at all. Adding it after may result in the controls briefly appearing before being hidden.
So, on my web app's home page I have a birthday (mm/dd/yy) select fields however the drop down is being cut off by the next section of the homepage's background.
Here's the relevant CSS styling for the select:
.selectify .option {
background: none repeat scroll 0 0 #FFFFFF;
border-top: 0 none;
color: #999999;
cursor: pointer;
padding: 5px 20px;
}
And an image:
How can I get the drop down to go over the secondary background section?
Cheers!
After being given the link:
.banner has a style of overflow:hidden;. This is what is causing it to hide.
Delete it from the styles of banner.
Then, you have a class called container middel-class. Change this to just middel-class.
Then put container INSIDE middel-class. eg:
<div class='middel-class'>
<div class='container'>
.. <!-- rest of code as normal -->
</div> <!-- end of container -->
</div> <!-- end of middel-class -->
Also, it's middle, not middel, but it doesn't really matter :P
I cant say for sure without any code example of full place. This bug can be for few reasons
1.) Somewhere on a parent div (where located dropdown) you are using overflow:hidden - try delete it and see what happens
2.) also there is can be wrong z-index directly on the dropdown
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.
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>
