Could not resolve the entity from <apex:inputField> value binding '{!Opportunities.Name}'. <apex:inputField> can only be used with SObjects, or objects that are Visualforce field component resolvable.

Hi,
 i created an apex class in that one i want to add each Opportunity in to list of Opportunities but in vf page i am getting an error "Could not resolve the entity from <apex:inputField> value binding '{!Opportunities.Name}'.  <apex:inputField> can only be used with SObjects, or objects that are Visualforce field component resolvable."
Here is my code : 
Apex code::
public class Opportunity_List {
    public List<Opportunity> Opportunities {set;get;}
    public Opportunity Oppos {set;get;}
    public Opportunity_List(){
        Opportunities = new List<Opportunity>();
        Oppos = new Opportunity();
    }
    public void add(){
        Opportunities.add(Oppos);
       
    }
    public void cancel(){
        Opportunities.clear();
    }

}
VF Code::
<apex:page controller="Opportunity_List" >
    <apex:form>
    	<apex:pageBlock title="Opportunity">
            <apex:pageBlockButtons>
                	<apex:commandButton value="ADD" action="{!add}" />
                    <apex:commandButton value="Clear" action="{!cancel}" />
                </apex:pageBlockButtons>
        	<apex:pageBlockSection  >
                <apex:inputField value="{!Opportunities.Name}" />
                <apex:inputField value="{!Opportunities.LeadSource}" />
                <apex:inputField value="{!Opportunities.ExpectedRevenue}" />
                <apex:inputField value="{!Opportunities.NextStep}" />
            </apex:pageBlockSection>
        </apex:pageBlock>
    </apex:form>
</apex:page>

HI Krishna ,
for resolve this error you have need to use <apex:repeat> tag.

use below code : 
<apex:page controller="Opportunity_List" >
    <apex:form>
    	<apex:pageBlock title="Opportunity">
            <apex:pageBlockButtons>
                	<apex:commandButton value="ADD" action="{!add}" />
                    <apex:commandButton value="Clear" action="{!cancel}" />
                </apex:pageBlockButtons>
        	<apex:pageBlockSection  >
                <apex:repeat value="{!Opportunities}" var="o">
                 <apex:inputField value="{!o.Name}" />
                 <apex:inputField value="{!o.LeadSource}" />
                 <apex:inputField value="{!o.ExpectedRevenue}" />
                 <apex:inputField value="{!o.NextStep}" />
                </apex:repeat>
            </apex:pageBlockSection>
        </apex:pageBlock>
    </apex:form>
</apex:page>
