I am trying to figure out how to enable vertical overflow for a jqueryui controlgroup selectmenu. The content is dynamic, so there are container drops and refreshes in play. Everything works, but I cannot get the css to work on a selectmenu when it's part of a controlgroup. (Standalone selectmenu works fine)
html div holder:
<div id="info1" class="info1" style="font-size:.9em;">
code:
$('#info1').empty();
$('<button id="infofirst" name="infofirst" data-icon="ui-icon-seek-first">First</button><button id="infoprevious" name="infoprevious">Previous</button>').appendTo('#info1');
while(countera-1 < sp){
$('<label for="infolist'+countera+'">'+countera+'</label><input type="radio" name="infolist" id="infolist'+countera+'" value='+countera+'>'
).appendTo('#info1');
countera++;}
$('<select id="listmoreinfo1" name="listmoreinfo1"><option disabled selected>More info... ('+tp+' Total)</option>').appendTo( '#info1' );
var counter = 1;
while(tp+1 > counter){
$('<option value="'+counter+'">Entry '+counter+' of '+tp+'</option>').appendTo( '#listmoreinfo1' );
counter++;
}
$('<button id="infonext" name="infonext">Next</button><button id="infolast" name="infolast">Last</button>').appendTo( '#info1' );
$( ".info1" ).controlgroup();
$( ".info1" ).controlgroup("refresh");
$(".listmoreinfo1")
.selectmenu({
classes:{
"overflow2"
}
});
$('#infolist'+p).prop('checked', true);
$( ".info1" ).controlgroup("refresh");
and style
.overflow2 {
height:200px;
overflow-y:scroll;
}
I'm thinking there has to be a simple solution that I am just missing.
Many Thanks.
Well I finally found a solution on my own....
.ui-autocomplete{overflow-y:scroll;height:200px;overflow-x:hidden;}
This is the only way I found to be able to handle the overflow of the dropdown list.

Is there a way to hide a whole div if part of it is empty? For example if "dd" is empty as shown below can I hide the whole class "test" so the keyword Restrictions does not show either. I tried .test dd:empty { display: none; } but this does not work. thanks!
<div class="test"><dt>Restrictions:</dt>
<dd></dd></div>
I don't think there's any easy way to do what you're talking about with just CSS. Better to test it server-side if you can. But if you can't here's some JS that will do the job.
<script type="text/javascript">
// handles multiple dt/dd pairs per div and hides them each conditionally
function hideIfEmpty() {
// get all the elements with class test
var els = document.getElementsByTagName('dl');
// for every 'test' div we find, go through and hide the appropriate elements
Array.prototype.map.call(els, function(el) {
var children = el.childNodes;
var ddEmpty = false;
for(var i = children.length - 1; i >= 0; i--) {
if(children[i].tagName === 'DD' && !children[i].innerHTML.trim()) {
ddEmpty = true;
} else if(children[i].tagName === 'DT') {
if(ddEmpty) {
children[i].style.display = 'none';
}
// reset the flag
ddEmpty = false;
}
}
});
}
window.addEventListener('load', hideIfEmpty);
</script>
<div class="test">
<div style="clear: both;"></div>
<dl>
<dt>Restrictions:</dt>
<dd></dd>
<dt>Other Restrictions:</dt>
<dd>Since I have content, I won't be hidden.</dd>
</dl>
</div>
Just a fair warning: the code uses some functions that may not exist in older IE, such as Array.prototype.map, String.prototype.trim, and addEventListener. There are polyfills available for these and you could also write your own pretty easily (or just do it with a for loop instead).
CSS alone can't do that. Either, you need a javascript to retrieve empty elements and hide their parents, or your CMS applies special CSS classes if there's no content.
Put as an answer as requested by #Barett.
You could update your CSS to be
.test{
display: none;
color: transparent;
}
This would make the text transparent too, but display:none should hide it anyway.
To make the div with the id test ONLY show when the dd tag is EMPTY, and you can use jQuery, try the following JavaScript along with the CSS:
if($("dd").html().length ==0)
{show();
}
Note: this solution requires jQuery, which is a JavaScript library.
html
<p> Tags:<input name="tags" id="tags" /></p>
jquery
$('#tags').tagit( {tagLimit:3});
I want to control the size of input field,how can i do that ?
If you look at the dynamic HTML that is generated by the tag-it plugin, ul.tagit is the class assigned to the UL that is generated. So to set the width to 200px in your CSS set:
ul.tagit {
width: 200px;
}
(function( $ ) {
$.fn.extend({
tagit: function (params) {
return this.each(function () {
console.log(params);
console.log(params['tagLimit'] );
$(this).attr('maxLength', params.tagLimit );
$(this).parent().css('maxwidth', params.tagLimit );
$(this).parent().css('width', params.tagLimit );
});
}
} )
}( jQuery ));
But you can do it directly by jQuery too, like below:
var _width = 3;
$("p input").each( function() {
$(this).css('width', _width);
$(this).css('maxWidth', _width);
})
Since I had tag-it being used in multiple places, I decided to do it in Javascript. The size needs to be big enough that it doesn't do to a double line when you add tags to it. The basic code is:
// adjust tag it size
$("ul.tagit").attr("style", "width:450px;")
Offcourse, you can decide to choose something other than 450px.
However, I also wanted to line it up with other jquery-ui buttons, which I styled with ul, instead of li, so they would have a fairly snug fit with the search box. The bottom margin needs to be adjusted to have it line up more precisely with the buttons. Here is the code for that.
// adjust tag it size and line it up with buttons
$("ul.tagit").attr("style", "width:450px; display:inline-block; margin-bottom:-10px")
Hey my question is how they made that, that the bar over and under the text fade in when the site is displayed ?

They probably set a jQuery event to automatically trigger the animation upon $( document ).ready
$(function() {
$("#progress-bar").toggleClass("top-bar-animation");
});
And then in their CSS, they have something like:
.top-bar-animation {
//animation code here
}
A friend and myself are trying to workaround IE (7/8). We have built a canonical example here:
http://www.mathgladiator.com/share/ie-select-bug-hover-css-menus.htm
Using a CSS menu, we would like to have selects in them. However, in IE, the menu goes away when you interact with the select box. We believe this has to do with a bug in how selects affect events.
Is there a workaround? At least with pure CSS or DOM hacks?
I do not think there is a pure CSS way around this. This is due to a very common bug to the way IE handles events on select elements.
You can however work around it with Javascript:
<script type="text/javascript">
$(document).ready(function () {
$('.nav_element a').mouseover(function() {
$('.submenu').hide();
$(this).parent().find('.submenu').show();
});
$('.submenu').mouseover(function() {
$(this).show();
});
$('.submenu').mouseout(function (e) {
// Do not close if going over to a select element
if (e.target.tagName.toLowerCase() == 'select') return;
$(this).hide();
});
});
</script>
The code above uses jQuery.
Here is a way to improver select behavior in IE7/8, but it does not fix the issue
Change DOCTYPE
<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.0 Transitional//EN">
Add script
<script>
function ddlOut(e) {
setTimeout(function() { e.className = e.className.replace(' over', ''); }, 1000)
}
</script>
Add css
#nav .over div.submenu
{
display: block;
}
#nav .nav_element{
behavior: expression(
this.onmouseover = new Function("this.className += ' over'"),
this.onmouseout = new Function("ddlOut(this)"),
this.style.behavior = null
);
}
It will work better at least but of course not perfect.
My advice is to change select control to html equivalent. I use OboutDropDown that has a nice view. There are many implementations that can suite you needs.
First you need to expand the :hover surface underneath your menu.
So in your css add width:310px;height:220px to #nav .nav_element a.
(also add a class or an id on the second div styled with top:220px)
Now you just need to simulate a mousedown triggered when you click on the select which will halt when the selection between the options is done - you can probably do the last part if you check for the onfocus state of the select which will stop the mousedown.
Edit : Problem wasn't related Event Propagation, if you want to know how to stop propagation in jQuery, then use event.stopPropagation();
When user moves his/her mouse over <span> element my jQuery code appends an <img>into this <span> element and when he moves out his mouse off <span> than the element appended is removed. It helps people to edit the field when clicking on the appended <img> element.
The reason I used append() method to add <img> into <span> is because I want to keep <img> element visible when user moves his mouse over to appended <img> element (<img> is becoming <span>'s child element) But it didn't happen and when user moves his mouse over it <img> is being deleted. I am thinking it is because event propagation but I couldn't find how to activate it in jQuery as we do with addEventListener in Firefox based browsers.
Here is the code :
JQuery Code :
$(document).ready(function() {
$('.EditEnabled').bind("mouseover", ShowEditFields);
$(".EditEnabled").bind("mouseout", HideEditFields);
});
function ShowEditFields(event) {
$(event.target).append(" <img id='editImg' src='images/edit.png' style='margin-bottom:-3px'/>");
}
function HideEditFields(event) {
$(event.target).children("#editImg").remove();
}
Simple HTML :
<span id="something" class="EditEnabled">Something Here</span>
Can you explain my how to solve it.
Thank you.
You want to use the jQuery mouseenter and mouseleave events, not mousover and mouseout. The reason is that mouseout will fire when you move the mouse over the img.
Thankfully, jQuery combines this into a hover method:
$(document).ready(function() {
$('.EditEnabled').hover(ShowEditFields, HideEditFields);
});
However I agree with the other answer that you should use CSS to do this vs. manipulating the DOM. I would just use the :hover pseudo selector, and then add special support for IE6.
CSS
span.EditEnabled img { display: none }
span.EditEnabled:hover img,
span.EditEnabled.hover img { display: block }
Make sure you have the img in the span in your HTML to begin with, and that is all you need for most browsers and IE7+
To support IE6 add:
<!--[if lte IE 6]>
<script type="text/javascript">
$(function(){
$(".EditEnabled").hover(
function(){ $(this).addClass('hover') },
function(){ $(this).removeClass('hover')}
);
});
</script>
<![endif]-->
Firstly, I would avoid as much DOM manipulation as you can. The ideal scenario is to construct your markup like this:
<span class="editEnabled">Some data<img ...></span>
with CSS:
span.editEnabled img { display: none; }
span.editEnabled img.visible { display: inline; }
and Javascript:
$(function() {
$("span.editEnabled").hover(function() {
$(this).children("img").addClass("visible");
}, function() {
$(this).children("img").removeClass("visible");
});
});
That should pretty much do it.
I would avoid the jQuery effects as making things visible will make them block level elements rather than inline like you want.
I've found another answer actually, the way I am looking for. It might not be a best practice but at least I've found out how to solve that.
$(document).ready(function() {
// $('.EditEnabled').bind("mouseenter", ShowEditFields);
// $(".EditEnabled").bind("mouseleave", HideEditFields);
$(".EditEnabled").hover(ShowEditFields, HideEditFields);
});
function ShowEditFields(event) {
var target = $(event.target);
if (target.is(":has(#editImg)") == false)
target.append(" <img id='editImg' src='images/edit.png' style='margin-bottom:-3px;display:inline'></img>");
}
function HideEditFields(event) {
// event.stopPropagation();
// if ($(event.relatedTarget).is("#editImg") == false)
$(event.target).children("#editImg").remove();
}
