Appearance
In this article, you will find information about the styling options and rendering of the Telerik UI for ASP.NET Core MultiSelect.
For a live example, visit the Appearance Demo of the MultiSelect.
Options
The MultiSelect supports the following styling options:
-
Size—configures the overall size of the component. -
Rounded—configures the border radius of the component. -
FillMode—configures how the color is applied to the component.
Size
The Size option controls the size of the MultiSelect. The k-input-{size} class, which is applied to the wrapping span element of the MultiSelect, reflects the value of the Size option.
The following values are available for the Size option:
-
Small—small size (applies thek-input-smclass to the wrapping span element) -
Medium—medium size (applies thek-input-mdclass to the wrapping span element) -
Large—large size (applies thek-input-lgclass to the wrapping span element) -
None—unset.
The following example demonstrates how to set Size in the declaration of the MultiSelect:
@(Html.Kendo().MultiSelect()
.Name("multiselect")
.DownArrow()
.Placeholder("Select...")
.Size(ComponentSize.Large)
.BindTo(new List<SelectListItem>()
{
new SelectListItem() {
Text = "Item1", Value ="1"
},
new SelectListItem() {
Text = "Item2", Value ="2"
},
new SelectListItem() {
Text = "Item3", Value ="3"
}
})
)
@{
var multiSelect_data = new List<SelectListItem>()
{
new SelectListItem() {Text = "Item1", Value ="1"},
new SelectListItem() {Text = "Item2", Value ="2"},
new SelectListItem() {Text = "Item3", Value ="3"}
};
}
<kendo-multiselect name="multiselect"
down-arrow="true"
placeholder="Select..."
size="ComponentSize.Large"
bind-to="multiSelect_data">
</kendo-multiselect>
The default size value is Medium and it is applied to the span wrapping element through the k-input-md class.
Below is the HTML of the MultiSelect that is affected from the Size configuration. The changes are applied to the span.k-multiselect wrapping element and to the span.k-chip elements:
<span class="k-multiselect k-input k-multiselect-clearable k-input-lg">
...
<span class="k-chip k-chip-lg k-rounded-lg k-chip-solid k-chip-solid-base" aria-setsize="2"></span>
</span>
Rounded
The Rounded option controls the border radius of the MultiSelect. The class that corresponds to the Rounded option is k-rounded-{rounded}.
The following values are available for the Rounded option:
-
Small—small border radius (applies thek-rounded-smclass to the wrapping span element) -
Medium—medium border radius (applies thek-rounded-mdclass to the wrapping span element) -
Large—large border radius (applies thek-rounded-lgclass to the wrapping span element) -
Full—largest (ellipse-like) border radius (applies thek-rounded-fullclass to the wrapping span element) -
None—unset.
The following example demonstrates how to set Rounded in the declaration of the MultiSelect:
@(Html.Kendo().MultiSelect()
.Name("multiselect")
.DownArrow()
.Placeholder("Select...")
.Rounded(Rounded.Medium)
.BindTo(new List<SelectListItem>()
{
new SelectListItem() {
Text = "Item1", Value ="1"
},
new SelectListItem() {
Text = "Item2", Value ="2"
},
new SelectListItem() {
Text = "Item3", Value ="3"
}
})
)
@{
var multiSelect_data = new List<SelectListItem>()
{
new SelectListItem() {Text = "Item1", Value ="1"},
new SelectListItem() {Text = "Item2", Value ="2"},
new SelectListItem() {Text = "Item3", Value ="3"}
};
}
<kendo-multiselect name="multiselect"
down-arrow="true"
placeholder="Select..."
rounded="Rounded.Medium"
bind-to="multiSelect_data">
</kendo-multiselect>
The default rounded value is Full. It applies the k-rounded-full class to the span.k-multiselect wrapping element that contains the HTML of the component. The class is also applied to the span.k-chip element which contains the HTML of the tags.
The rendering of the MultiSelect with Rounded.Medium set:
<span class="k-multiselect k-input k-multiselect-clearable k-input-solid k-input-lg k-rounded-md">
...
<span class="k-chip k-chip-lg k-rounded-md k-chip-solid k-chip-solid-base" aria-setsize="2"></span>
</span>
FillMode
The FillMode option controls how the color of the tags is applied. The structure of the class is k-input-{fillMode}.
The following values are available for the FillMode option:
-
Solid—applies thek-input-solidclass to the wrapping span element -
Flat—applies thek-input-flatclass to the wrapping span element -
Outline—applies thek-input-outlineclass to the wrapping span element -
None—unset.
The default value is Solid and it is applied to the span.k-multiselect wrapping element through the k-input-solid class and to the span.k-chip elements through the .k-chip-solid .k-chip-solid-base classes.
The following example demonstrates how to set FillMode in the declaration of the MultiSelect:
@(Html.Kendo().MultiSelect()
.Name("multiselect")
.DownArrow()
.Placeholder("Select...")
.FillMode(FillMode.Outline)
.BindTo(new List<SelectListItem>()
{
new SelectListItem() {
Text = "Item1", Value ="1"
},
new SelectListItem() {
Text = "Item2", Value ="2"
},
new SelectListItem() {
Text = "Item3", Value ="3"
}
})
)
@{
var multiSelect_data = new List<SelectListItem>()
{
new SelectListItem() {Text = "Item1", Value ="1"},
new SelectListItem() {Text = "Item2", Value ="2"},
new SelectListItem() {Text = "Item3", Value ="3"}
};
}
<kendo-multiselect name="multiselect"
down-arrow="true"
placeholder="Select..."
fill-mode="FillMode.Outline"
bind-to="multiSelect_data">
</kendo-multiselect>
The FillMode.Outline value is reflected through the respective classes applied to the span.k-multiselect wrapping element and to the span.k-chip elements:
<span class="k-multiselect k-input k-multiselect-clearable k-input-outline k-input-lg k-rounded-md">
...
<span class="k-chip k-chip-lg k-rounded-md k-chip-outline k-chip-outline-base" aria-setsize="2"></span>
</span>
Rendering
Starting with version R1 2022, the component has a new rendering. For additional information on the decision behind these changes, visit the Components Rendering Overview article.
To review the latest rendering of the component, refer to the HTML specifications in the Kendo UI Themes Monorepo. The tests folder of the repository contains the rendering for all flavors of the components, providing a clear reference for how their elements are structured. The rendering information can help you customize a component's appearance and behavior by applying custom CSS or JavaScript to suit specific design or functional requirements.
