I am trying to provide my users with 2 ways to filter a list; either by a data-filter and by a couple of buttons.
The buttons use class attributes to remove groups of list items. In my real application, there are about 8 categories that I need to switch between; or show them all.
So I wrote the routine 'filterCategories' which .hide() all of the items, then .show() just the category that I want to display. This works fine. (I can't use nested lists because the items are arranged in a specific order - not in category order)
However, after I .hide() and .show(), the data-filter no longer works on the items that were hidden. The .hide() seems to remove the items from the listview-filter.
I have tried a listview('refresh') and that does not help.
Is there some other way to do this?
Thanks,
Jeff
(cut down version below... click on "Remove 10s" then type 22 in the search bar. Only "Item 22" should appear. )

I had the exact same problem and after much troubleshooting I found the solution:
Rather than using $('li-element').hide() or .show(), you must add or remove class "ui-screen-hidden".
$('li-element').removeClass("ui-screen-hidden");
OR
$('li-element').addClass("ui-screen-hidden");

So I am trying to dynamically (using javascript) add an input field in a form by clicking the button "Add". The semantic-ui dropdown css styling to the first field since it is not added with javascript. However, after I press add, a new field created by the css styling is not applied.
Here is a link to a demo.

Here is my code

fiddle: https://jsfiddle.net/8pcfz2a7/
you should call $('.dropdown').dropdown(); for new elements as well.
so add $('.dropdown').dropdown(); to end of your click handler.
you can also put this in a function called update_ui, for reuse code.
Context: We can't use the full semantic ui library due to security reason. So I want to try the individual semantic ui dropdown module, because it is very good solution for a lot of data entry scenarios.
The following code works when I reference the full library, but doesn't work when I reference the individual module.
<!DOCTYPE html>
<html>
<head>
<meta name="viewport" content="width=device-width" />
<link rel="stylesheet" href="~/lib/semantic-ui-dropdown/dropdown.css"/>
</head>
<body>
<select class="ui dropdown">
<option value="1">Email</option>
<option value="2">Text</option>
</select>
<script src="~/lib/jQuery/dist/jquery.js"></script>
<script src="~/lib/semantic-ui-dropdown/index.js"></script>
<script src="~/lib/semantic-ui-dropdown/dropdown.js"></script>
<script>
$('.ui.dropdown').dropdown();
</script>
</body>
</html>
I dug into the problem, and find the generated html is like the following:
<div class="ui dropdown selection" tabindex="0">
<select>
<option value="1">Email</option>
<option value="2">Text</option>
</select>
<i class="dropdown icon"></i>
<div class="text">Email</div>
<div class="menu" tabindex="-1">
<div class="item active selected" data-value="1">Email</div>
<div class="item" data-value="2">Text</div>
</div></div>
The result is a big UI box like control showing "Email" and when you click on it, nothing happens.
I think the problem maybe the "selection" class added to the end of the top level div. Just my guess.
Could anyone point out where I did wrong? Really want to get this working. Love the semantic ui dropdown solution.
found the cause of this problem.
semantic-ui-dropdown has an dependency on semantic-ui-transition...
just reference semantic-ui-transition before semantic-ui-dropdown will do.
just add this to the end script in your index.html
<script>
function callDropdown(){
$('.ui.dropdown')
.dropdown();
}
setTimeout(callDropdown, 3000);
This is the chunk of my code
<div class="form-control">
<div class="input-group">
<span class="input-group-addon">
<input type="text" id = "fromuser"></input>
<select id="combobox">
<option value="">Select one...</option>
<option value="abc">abc</option>
<option value="cde">cde</option>
<option value="xyz">xyz</option>
</select>
</span>
<button type="submit">Submit</button>
</div>
</div>
What I am trying to achieve is that the User can either Type the value or select from the dropdown list. The challenge here is that the Input from Keyboard will be different from that given in dropdown. For example, the dropdown has three character string options but the user can type a number such as 10, 20, 30 etc.
Is this type of input allowed possible? If so, can someone help me.
The Closest I could come to my problem is by dropping the select and use autocomplete . The full test code is as follows:-
<!doctype html>
<html lang="en">
<head>
<meta charset="utf-8">
<meta name="viewport" content="width=device-width, initial-scale=1">
<title>jQuery UI Autocomplete - Default functionality</title>
<link rel="stylesheet" href="//code.jquery.com/ui/1.12.1/themes/base/jquery-ui.css">
<script src="https://code.jquery.com/jquery-1.12.4.js"></script>
<script src="https://code.jquery.com/ui/1.12.1/jquery-ui.js"></script>
<script>
$( function() {
var availableTags = [
"abc",
"def",
"xyz"
];
$( "#tags" ).autocomplete({
source: availableTags
});
} );
function myFunction(){
var NameValue = document.forms["FormName"]["tags"].value;
window.alert(NameValue);
}
</script>
</head>
<body>
<form name="FormName" method="post" />
<div class="ui-widget" >
<input name= "tags" id="tags" type="text" onchange="myFunction()"/>
<button name="btn-signup" type="submit" value="Submit">Submit</button>
</div>
</form>
</body>
</html>
I know this is the final solution but maybe a way ahead.
I have used Bootstrap 3 to create a page with a fixed nav bar top. In the body I have elements with #anchor tags. When I click from the nav bar, the element position is displayed but there seems to be a misalignment of the row (approximately the height of the nav bar) - BS3.0 docs say you need to put the padding-top of the body to the height of the nav bar (50px in this case) and have the body position relative. There have been posts about the docs not being correct and I can't seem to fix this...
here is a fiddle: http://jsfiddle.net/richnasser/fkLh9sf4/1/ and the full screen http://jsfiddle.net/richnasser/fkLh9sf4/1/embedded/result/
Click on 'about' and the scrolling should stop at the top of the Santa Claus header. In my browser (Chrome) it goes well beyond that, hiding the headline. Any insights would be greatly appreciated.

You can achieve this using simple JavaScript. Below Fiddle will help you to figure it out.
http://jsfiddle.net/ianclark001/aShQL/
In the above fiddle code, update the fromTop height as per your fixed header height.
var fromTop = 50; // Give Your fixed header height
And also you can find more information at:
offsetting an html anchor to adjust for fixed header
I have used this solution, with no javascript, only css, and worked for me:
Give your anchor a class:
<a class="anchor" id="top"></a>
You can then position the anchor an offset higher or lower than where
it actually appears on the page, by making it a block element and
relatively positioning it. -250px will position the anchor up 250px
a.anchor {
display: block;
position: relative;
top: -250px;
visibility: hidden;
}
You can adjust the top to the size of you navbar.

You're getting messed up by the enhancement which jQM does. Your button is getting rewritten to:
<span class="ui-btn-inner ui-btn-corner-all"><span class="ui-btn-text">Primary Phone</span>
<span class="ui-icon ui-icon-home ui-icon-shadow"></span></span>
<button class="cl_pre_phone1 ui-btn-hidden" type="submit" data-theme="a" data-icon="home" aria-disabled="false">Primary Phone</button>
One way round this would be to change the call inside the callback to:
$(".cl_pre_phone1").attr("href", "http://yahoo.com").parent().find(".ui-btn-text").text("Yahoo");
or you could replace the whole ui-block-a div.
