Hi,

Please follow the below code and steps to create list buttons in VF Page

  • Create a list view button
  • Add the list view button to Listview layout by going to the Search Layout setting.
VF Page
  
standardController="Opportunity" recordSetVar="opportunities" extensions="ListViewButtonDemo">
    <apex:form >
        <html>
            <head>
            </head>
            <body>
                <apex:pageMessages />
                <table>
                    <tr>
                        <th>Name</th>
                    </tr>
                    <apex:repeat value="{!opportunities}" var="o">
                        <tr>
                            <td>
                                <apex:inputField value="{!o.Name}"/>
                            </td>
                        </tr>
