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 below 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; }
