Hi Gopi.MCA,
I want to increase like this width
In this case, you will need to use the local reference of this sumoselect.css, you can
download the related two files ( jquery.sumoselect.min.js and sumoselect.css).
Like below in your project:

Then, in your local sumoselect.css, change
.SumoSelect {
width: 200px;
}
to:
.SumoSelect {
width: 300px;//or any other width you want
}
or to:
.SumoSelect {
width: inherit;
}
then you can rewrite this style in your current page.
Please refer to below demo:
<html xmlns="http://www.w3.org/1999/xhtml">
<head runat="server">
<title></title>
<script src="http://ajax.googleapis.com/ajax/libs/jquery/1.9.0/jquery.min.js"></script>
<script src="https://cdnjs.cloudflare.com/ajax/libs/jquery.sumoselect/3.0.2/jquery.sumoselect.min.js"></script>
<link href="Scripts/sumoselect.css" rel="stylesheet" />
<%--<link rel="stylesheet" href="https://cdnjs.cloudflare.com/ajax/libs/jquery.sumoselect/3.0.2/sumoselect.min.css" />--%>
<script>
$(document).ready(function () {
$('#ListBox1').SumoSelect({search: true, searchText: 'Enter here.'});
});
</script>
<style>
.SumoSelect {
width: 300px;
}
</style>
</head>
<body>
<form id="form1" runat="server">
<div>
<asp:ListBox ID="ListBox1" runat="server" selectionmode="Multiple" DataTextField="UName" DataValueField="UID" DataSourceID="SqlDataSource1"></asp:ListBox>
<asp:SqlDataSource ID="SqlDataSource1" runat="server" ConnectionString="Data Source=.;Initial Catalog=DatabaseTestPool;Integrated Security=True" SelectCommand="select UID,UName from Users"></asp:SqlDataSource>
</div>
</form>
</body>
</html>
You will get the result like below:

Best Regard,
