All Syncfusion Blazor packages are available on nuget.org. See the NuGet packages topic for details.
Add import namespaces
After the packages are installed, open the ~/_Imports.razor file and import the Syncfusion.Blazor and Syncfusion.Blazor.DropDowns namespaces.
@using Syncfusion.Blazor
@using Syncfusion.Blazor.DropDownsRegister Syncfusion® Blazor service
Register the Syncfusion® Blazor service in the Program.cs file of your Blazor WebAssembly App.
....
using Syncfusion.Blazor;
....
builder.Services.AddSyncfusionBlazor();
....Add stylesheet and script resources
The theme stylesheet and script can be accessed from NuGet through Static Web Assets. Include the stylesheet and script references in the ~/index.html file.
<link href="_content/Syncfusion.Blazor.Themes/fluent2.css" rel="stylesheet" />
....
<script src="_content/Syncfusion.Blazor.Core/scripts/syncfusion-blazor.min.js" type="text/javascript"></script>NOTE
Check out the Blazor Themes topic to discover various methods (Static Web Assets, CDN, and CRG) for referencing themes in the Blazor application. Also, check out the Adding Script Reference topic to learn different approaches for adding script references in the Blazor application.
Add Syncfusion® Blazor Mention component
Add the Syncfusion® Blazor Mention component in the ~/Pages/Index.razor file.
@using Syncfusion.Blazor.DropDowns
<SfMention TItem="PersonData" DataSource="@EmailData">
<TargetComponent>
<div id="commentsMention" placeHolder="Type @@ and tag user" ></div>
</TargetComponent>
<ChildContent>
<MentionFieldSettings Text="Name"></MentionFieldSettings>
</ChildContent>
</SfMention>
<style>
#commentsMention {
min-height: 100px;
border: 1px solid #D7D7D7;
border-radius: 4px;
padding: 8px;
font-size: 14px;
width: 600px;
}
div#commentsMention[placeholder]:empty:before {
content: attr(placeholder);
color: #555;
}
</style>
@code {
public class PersonData
{
public string Name { get; set; }
public string EmailId { get; set; }
public string EmployeeImage { get; set; }
}
List<PersonData> EmailData = new List<PersonData> {
new PersonData() { Name="Selma Rose", EmployeeImage="7", EmailId="[email protected]" },
new PersonData() { Name="Russo Kay", EmployeeImage="8", EmailId="[email protected]" },
new PersonData() { Name="Camden Kate", EmployeeImage="9", EmailId="[email protected]" }
};
}- Press ctrl+F5 or ⌘+F5 (macOS) to launch the application. This will render the Syncfusion® Blazor Mention component in the default web browser.
Mention target
The Target property of the Mention component allows you to specify an element on the page to which the mention element should be attached. This can be useful when you want to display the mention element in a specific location on the page. For example, you might use the Target property to attach the mention element to a specific div element or to a specific input field or to a specific textarea field. To specify the target element, you can pass a CSS selector, a DOM element.
In the bellow example, the Target property of the Mention component is set to the CSS selector #mentionTarget, which matches the textarea element with an id of mentionTarget. The mention element will be appended to the textarea element as a child element, allowing the user to select or mention a specific entity within the textarea.
@using Syncfusion.Blazor.DropDowns
<textarea id="mentionTarget" placeHolder="Type @@ and tag user"></textarea>
<SfMention TItem="PersonData" Target="#mentionTarget" DataSource="@EmailData">
<ChildContent>
<MentionFieldSettings Text="Name"></MentionFieldSettings>
</ChildContent>
</SfMention>
<style>
#mentionTarget {
min-height: 100px;
border: 1px solid #D7D7D7;
border-radius: 4px;
padding: 8px;
font-size: 14px;
width: 600px;
}
div#mentionTarget[placeholder]:empty:before {
content: attr(placeholder);
color: #555;
}
</style>
@code {
public class PersonData
{
public string Name { get; set; }
public string EmailId { get; set; }
public string EmployeeImage { get; set; }
}
List<PersonData> EmailData = new List<PersonData> {
new PersonData() { Name="Selma Rose", EmployeeImage="7", EmailId="[email protected]" },
new PersonData() { Name="Russo Kay", EmployeeImage="8", EmailId="[email protected]" },
new PersonData() { Name="Camden Kate", EmployeeImage="9", EmailId="[email protected]" }
};
}
