I have a select2 in a bootstrap v4 dropdown. I load the options into the select2 when the dropdown is triggered.
The select2 contains some items with long names, and if the select2 is opened, I would like to show the full width even though that is wider than the dropdown.
I have tried select2({width: 'resolve'}) and select2({width: '200%'})
in the select2:opening and select2:open event handlers but they throw exceptions. If I initialize the select2 with width:200%, it is too big if it isn't opened.
Is this possible? Any ideas? Thanks.
It sounds like you are looking for the dropdownAutoWidth option. This should automatically resize the dropdown based on the available room.

JSF has autocomplete functionality with enablemanualInput but whenever I try to input a new value which is not present in the dropdown list it turns red and dropdown keeps open to show that no such entry is available. I want to replicate combobox functionality currently present in html/JQUERY UI. Is there any way to do so.
Hei guys.
I'm trying to add additional HTML elements below search box.. like checkboxes for filtering purposes.
But the added checkbox is not functional, you can't actually check it. I'm not sure but I think that search box is taking the focus from them... I created this jsFiddle so you guys can check it out.
http://jsfiddle.net/6wz2hLh0/
$("#e1").select2();
//Inserting additional HTML elements below search... filter in my case
$(".select2-search").after("<input type='checkbox'/>");
When the dropdown is open you can't even write in jsFiddle input's.
I tried commenting out various focus calls from source code with no luck.
Can any one point me in to right direction in source code what is causing this non stop search box focussing.
One thing to try is to have the checkbox element stop the mouse events from propagating. That seems to prevent them from getting to Select2, so Select2 cannot kill them.
$("<input type='checkbox'/>")
.insertAfter(".select2-search")
.on('mousedown mouseup click', function(e) { e.stopPropagation(); });

My guess is that this is because Select2 kills (stops propagation and prevents default) most events that occur within the dropdown. This is so Select2 doesn't leak events, but it also causes problems like not being able to catch click events or embed links.
When the dropdown is open you can't even write in jsFiddle input's.
This is because Select2 uses a mask that captures all events outside of the dropdown.

You are going to want to look through the source for killEvent, as this is the method Select2 uses that kills events. As most browsers listen for the click event for native controls, you probably want to remove this killEvent for dropdown clicks.
I want to achieve a selection box in the drop down window.(I'm using something like
<%= f.select(:season, options_for_select(['spring/fall', 'winter', 'summer'], 'spring/fall'))%>
for the selection box for now)
In this window, I want to have many icons. The user can select one of these icons. And the selected icon will be saved in the database as one attribute of the object.
Can I do this without JavaScript?
Yes it is possible to use the background-image property to set icons in a dropdown, but apparently it only works in Firefox
See this question for discussions of how to do it with JS putting images with options in a dropdown list
SO I have a select box that I fill dynamically. I discovered that once the SELECT gets longer than the page, it automatically becomes a dialog listview.... which is TERRIBLE!
When this happens, the page refreshes when the dialog is closed and my whole page starts over....
Has anyone experienced that and do you know how to shut it off?
Thanks!

You could use the native look and feel?
http://jquerymobile.com/demos/1.0.1/docs/forms/forms-all-native.html
Native form elements & buttons Although the framework automatically enhances form elements and buttons into touch input
optimized controls to streamline development, it's easy to tell jQuery
Mobile to leave these elements alone so the standard, native control
can be used instead.
Adding the data-role="none" attribute to any form or button element
tells the framework to not apply any enhanced styles or scripting. The
examples below all have this attribute in place to demonstrate the
effect. You may need to write custom styles to lay out your form
controls because we try to leave all the default styling intact.
I want to use a autocomplete combobox http://jqueryui.com/demos/autocomplete/#combobox within a modal dialog. However whenever I click on the down arrow (of the combobox) it causes a refresh that results in my modal window closing.
How do I stop the refresh from occuring? (I am still new to jQuery)
I am using UI 1.8 and jQuery 1.4.1.
The problem is discussed on the jQuery forum here:
http://forum.jquery.com/topic/autocomplete-combobox-problem-when-it-is-placed-inside-a-form-tag
They suggest several different ways of adjusting the source code of the autocomplete combo to fix it. The simplest one seems to be this:
Change the line that says
$("<button> </button>")
to
$("<button type=\"button\"> </button>")
this prevents the type="submit" from being inserted into the final button.
Ok I fixed my own problem by removing the form tag from around the combobox
