Prefix and Suffix
The MultiSelect component provides options for enhancing the user interface interactivity by adding custom content as prefix and suffix adornments.
The prefix and suffix input adornments are elements positioned before and after the MultiSelect input element, commonly used to clarify the expected data in the input, such as currency symbols or unit indicators, and provide direct functionality for the entered data, like password visibility toggles, formatting, and more.
Prefix
The prefix input adornment is placed before the MultiSelect field and provides an additional context that guides users in entering specific data, such as icons for currencies or unit indicators. To configure the Prefix functionality, use the PrefixOptions() configuration, which facilitates the following options:
-
Icon()—Inserts an icon before the MultiSelect element. The option accepts the name of an existing icon in the Kendo UI theme or SVG content. -
Template()—Adds custom content before the MultiSelect element. You can use a variety of templating options likeTemplateId(),TemplateHandler(), and more. -
Separator()—By default, the separator is visible. Disable theSeparator()option to remove the default separator of the prefix content.
The following example demonstrates how to set an icon as a prefix of the MultiSelect component.
@(Html.Kendo().MultiSelect()
.Name("customers")
.PrefixOptions(prefix => prefix.Icon("user"))
.Placeholder("Select customers...")
.DataTextField("ContactName")
.DataValueField("CustomerID")
.Height(400)
.ClearButton(true)
.AutoClose(false)
.DataSource(source =>
{
source.Read(read =>
{
read.Action("GetCustomers", "MultiSelect");
});
})
)
<kendo-multiselect name="customers"
placeholder="Select customers..."
datatextfield="ContactName"
datavaluefield="CustomerID"
height="400"
clear-button="true"
auto-close="false">
<prefix-options icon="user" />
<datasource type="DataSourceTagHelperType.Custom">
<transport>
<read url="@Url.Action("GetCustomers", "MultiSelect")" />
</transport>
</datasource>
</kendo-multiselect>
public IEnumerable<CustomerViewModel> GetCustomers()
{
using (var customers = GetContext())
{
return customers.Customers
.Select(customer => new CustomerViewModel
{
CustomerID = customer.CustomerID,
ContactName = customer.ContactName
}).ToList();
}
}
Suffix
The suffix input adornment is an element positioned after the input field. Usually, it offers direct functionality related to the entered data, such as toggles for password visibility, formatting options, or the ability to clear the input. Set up the Suffix functionality through the SuffixOptions() configuration that provides the following options:
-
Icon()—Adds an icon after the MultiSelect element. The option accepts the name of an existing icon in the Kendo UI theme or SVG content. -
Template()—Adds custom content for the suffix adornment of the MultiSelect. -
Separator()—By default, the separator is visible. Disable theSeparator()option to remove the default separator of the suffix content.
The following example demonstrates how to add a button as a suffix of the MultiSelect component.
@(Html.Kendo().MultiSelect()
.Name("customers")
.SuffixOptions(suffix => suffix.TemplateId("suffixTemplate"))
.Placeholder("Select customers...")
.DataTextField("ContactName")
.DataValueField("CustomerID")
.Height(400)
.ClearButton(true)
.AutoClose(false)
.DataSource(source =>
{
source.Read(read =>
{
read.Action("GetCustomers", "MultiSelect");
});
})
)
<script type="text/x-kendo-template" id="suffixTemplate">
@(Html.Kendo().Button()
.Name("suffix-button")
.Content("Cc")
.FillMode(ButtonFillMode.Flat)
.ToClientTemplate()
)
</script>
<kendo-multiselect name="customers"
placeholder="Select customers..."
datatextfield="ContactName"
datavaluefield="CustomerID"
height="400"
clear-button="true"
auto-close="false">
<suffix-options template-id="suffixTemplate" />
<datasource type="DataSourceTagHelperType.Custom">
<transport>
<read url="@Url.Action("GetCustomers", "MultiSelect")" />
</transport>
</datasource>
</kendo-multiselect>
<script type="text/html" id="suffixTemplate">
<kendo-button name="suffix-button" is-in-client-template="true"
fill-mode="ButtonFillMode.Flat">
Cc
</kendo-button>
</script>
public IEnumerable<CustomerViewModel> GetCustomers()
{
using (var customers = GetContext())
{
return customers.Customers
.Select(customer => new CustomerViewModel
{
CustomerID = customer.CustomerID,
ContactName = customer.ContactName
}).ToList();
}
}
