Replace Kendo default dropdownlist template by custom image? - drop-down-menu

What I want to do is when i click on my image, i want the kendo dorpdownlist to propose me some options. Is it possible ?
I tried to replace the defautl template of dropdownlist with CSS without success.
Here i try simply to replace the default black arrow of the dropdownlist, with no success.
SOURCE : http://docs.kendoui.com/getting-started/web/appearance-styling?x=54&y=12
-----------------------------HTML
<select id="customList" class="k-widget k-dropdown"></select>
-----------------------------Javascript
$("#customList").kendoDropDownList().data("kendoDropDownList");
-----------------------------CSS
#customList .k-icon .k-i-arrow-s
{
background-image:url('../../resources/img/components/addtab.png');
}
But what i really want to achieve is to replace completely the default template of the kendo dropdownlist and to have instead my image.

There are a couple of question to keep in mind:
The HTML element that contains the arrow is not a descendant of customList but descendant of a sibling. This is because KendoUI decorates original elements with others.
You are only re-defining background-image but you there is two additional CSS attributes that you need to redefine: background-position and background-size since it is defined in Kendo UI CSS files for offsetting k-i-arrow-s icon.
So, you should either do:
span.k-icon.k-i-arrow-s {
background-image:url('../../resources/img/components/addtab.png');
background-size: 16px 16px;
background-position: 0 0;
}
if you are ok with redefining every additional elements OR you do it programmatically defining a CSS:
.ob-style {
background-image:url('../../resources/img/components/addtab.png');
background-size: 16px 16px;
background-position: 0 0;
}
and a JavaScript:
var list = $("#customList").kendoDropDownList({...}).data("kendoDropDownList");
$(list.wrapper).find(".k-icon.k-i-arrow-s").addClass("ob-style");

jqGrid, checkbox not aligned to left on edit form. Bootstrap

I'm using jqGrid JS v5.3.0, with styleUI set to Bootstrap. On edit form, the checkbox (created by setting edittype option. also set editoptions: {value:"true:false"}) is aligned to the center of the form. Is there a way to make it align to the left?
Thanks in advance.
The reason for this is the setting in the bootstrap css
.EditTable td input,
.EditTable td select,
.EditTable td textarea {
width: 98%;
display: inline-block;
}
i.e this is caused from width:98%
To correct this there are a lot of ways.
The first one is to use editoptions to set a manual auto width with style options.
edittype : 'checkbox',
editoptions : {value:"true:false", "style":"width:auto"},
The second one (more elegant IMHO) is to set this in css for all check-boxes in the edit form like this:
<style>
.EditTable td input[type="checkbox"]
{
width :auto;
}
</style>
after loading the jqgrid bootstrap css file.

Reusing existing span with custom attributes in CKEditor while changing background color

When changing the background-color, CKEditor wraps the selected content in a span element where the inline style is set.
I have an application to create interactive videos: it is possible to stop the playback in desired moments and, in these pauses, the viewer can jump to key moments of the video, or answer to quizzes, returning to specific points of the video if the answer was wrong, and so on. To create this interactive layer above the player I use the CKEditor with some custom plugins to create the interactive elements.
One of the plugins is used to create span elements with a custom attribute data-player-control:
span[data-player-control] {
background-color: #3366FF;
color: #FFF;
border-radius: 10px;
padding: 10px;
}
<span data-player-control="play">My element</span>
The value of the data-player-control attribute is not fixed (it can be specified in the plugin), and it is used to control the exhibition of the video.
When the editor is used to change the element background color, it wraps the element text in a new span, what results in:
span[data-player-control] {
background-color: #3366FF;
color: #FFF;
border-radius: 10px;
padding: 10px;
}
<span data-player-control="play">
<span style="background-color:#FF0000">My element</span>
</span>
These two nested span elements, with two distinct background colors, are undesired.
What I need is the inline style to be applied to the existing span element, resulting in:
span[data-player-control] {
background-color: #3366FF;
color: #FFF;
border-radius: 10px;
padding: 10px;
}
<span data-player-control="play" style="background-color:#FF0000">
My element
</span>
How can this be achieved?
Using dataFilter or htmlFilter is not a feasible solution, as they are executed in input or output data, when entering or existing the inline instance of the CKEditor. Using a transformation also is not a solution, as it uses a simplified form to represent the elements, not the real DOM.
Is there any callback function to use while editing the content (so I can change the DOM according to my needs)?
A simple solution is to listen to the change event in the editor instance and then modify the DOM in event.editor.ui.contentsElement.$ as desired.
You can try to use custom styles definition which is used for adding background-color. The colorButton_backStyle can be set in the editor config.
To override span element with some custom attributes, you can use:
config.colorButton_backStyle = {
element: 'span',
styles: { 'background-color': '#(color)' },
overrides: { 'element': 'span', attributes: { 'data-player-control': 'play' } }
};
So basically overrides attribute is used when applying background-color and there is a span with such attribute - it is replaced (but then the attribute also gets removed ). You can add attributes:
config.colorButton_backStyle = {
element: 'span',
attributes: { 'data-player-control': 'play' },
styles: { 'background-color': '#(color)' },
overrides: { 'element': 'span', attributes: { 'data-player-control': 'play' } }
};
So that overriding span also has your attribute. The problem with this solution is that:
When applying background color to other elements, span will also have data-player-control attribute.
When removing background color, the whole span gets removed.
The above solution may not fit your needs. Maybe there is different approach to the problem you are trying to solve?
As I understand from the question you would like the HTML to have defined structure the whole time (not only as output data), is that correct? What problem is structure with nested spans causing in your application/implementation?

How to increase the height of filter toolbar placed on top of JQGRID

I have a jqgrid in which I have implemented the filter toolbar on top of the grid. Now I want to increase the height of all filter toolbar columns but I am not getting exact idea. I searched it on the web and got to know that it can be done by changing in .css file of the grid but not getting the exact code snippet.
Also I have to increase the height of grid rows.
$('#mytable').jqGrid('filterToolbar', {autosearch: true});
The height of the filter toolbar are set by some lines of ui.jqgrid.css. Default height is 20px. To increase it for example up to 30px you can add additional CSS style definitions to your page which overwrite the settings from ui.jqgrid.css. For example the following demo (and another one which uses no searching operations) uses the following styles
.ui-jqgrid .ui-search-table { height: 30px; }
.ui-jqgrid .ui-search-table .ui-search-oper { height: 30px; }
.ui-jqgrid .ui-jqgrid-htable .ui-search-toolbar th { height: 32px; }
It displays
I added to the demos the style described in the answer too just to improve the visibility of the input fields.

CKEditor config.stylesSet

I'm trying to get the dropdown styles option in CKEditor V4 configured. My test, shown below, does not work as expected. The dropdown style menu its self does display the "Green Check" option (label and the image used in the style) but its not applied to content of editor instance when used. I'm using the new inline editing feature (way cool it is too).
config.stylesSet = [
{ name: 'Green Check', element : 'ul li',
styles :
{
'background' : 'url(/images/bullets/greencheck.png) no-repeat top left;',
'list-style-type' : 'none;'
}
}
];
I specified the element element : 'ul li', because 'ul' obviously targets the ul element but when 'li' is specified, I get nothing in the dropdown menu or applied to content.
Here's more or less the complete style that I'm trying to configure...
ul.greencheck li{
list-style-type:none;
line-height:18px;
background: url(/images/bullets/greencheck.png) no-repeat center left;
padding-left:30px;
}
Any help gratefully received.
'ul li' isn't a valid element, you can use either 'ul' or 'li' but not both
You should remove also the ending semicolon in the styles 'none;' isn't valid, 'none' is the correct one
and instead of setting the inline styles it would be better to just apply a class to the UL and leave the styles to a separate css file.

CSS - Inheriting layered background images

CSS3 supports multiple background images, for example:
foo { background-image: url(/i/image1.jpg), url(/i/image2.jpg); }
I'd like to be able to add a secondary image to an element with a class though.
So for example, say you have a nav menu. And each item has a background image. When a nav item is selected you want to layer on another background image.
I do not see a way to 'add' a background image instead of redeclaring the whole background property. This is a pain because in order to do this with multi-backgrounds, you would have to write the base bg image over and over for each item if the items have unique images.
Ideally I'd be able to do something like this:
li { background: url(baseImage.jpg); }
li.selected { background: url(selectedIndicator.jpg); }
And have li.selected's end result appear the same if I did:
li.selected { background: url(baseImage.jpg), url(selectedIndicator.jpg); }
Update: I also tried the following with no luck (I believe backgrounds are not inherited..)
li { background: url(baseImage.jpg), none; }
li.selected { background: inherit, url(selectedIndicator.jpg); }
That is, in any case, not the way CSS inheritance works. inherit implies that an element should take on the attributes of it's parent element, not previous declarations affecting the same element.
What you want has been proposed as a way to make CSS more object-oriented, but the closest you will get is with a pre-processor like SASS.
For now you actually just have to re-state the first image along with the second.
I don't think this is possible, I think you'd have to redefine the whole rule every time.
For example, you could just add a "wrapper" around every item that has the initial background, with the actual item having a transparent background. Then add the background on the item itself when it's selected.
Additive CSS rules still aren't possible as far as I know.
You could try applying the second image to the ::after pseudo element:
li { background: url(baseImage.jpg); position: relative; }
li.selected::after {
content: '';
position: absolute;
width: 100%;
height: 100%;
background: url(selectedIndicator.jpg);
}
I had the same need as you recently.
I finally thought about it and solved using css variables.
::root { --selectdropdown: url( '../elements/expand-dark.svg' ); }
select.gender.female { background-image: var(--selectdropdown), url( '../elements/female-dark.svg' ); }
When you resetting the attribute, just specify the variable again in the list!
