Hello,

i have custom VF-Page which works for "edit"-mode. But i need this one also for adding new data. 
 

<apex:page standardController="Contact" extensions="TestFriends" showHeader="true" sidebar="true">
    <apex:slds />
    <div class="slds-scope">
        <apex:detail subject="{!contact.Id}" relatedList="true" inlineEdit="true"/>
        <apex:form >

            <apex:pageBlock title="Friends" id="data0">
                <ul class="slds-list--horizontal slds-has-cards--space has-selections">
                    <apex:repeat value="{!friends}" var="eve" >
                        <br></br> 
                    <li class="slds-list__item">
                        <div class="slds-card">
                            
                        
                        <div class="slds-card__header">Friend</div>
                        <div class="slds-tile slds-tile--board">
                            <p class="slds-tile__title slds-truncate"> 
                                <apex:outputField label="Name:" value="{!eve.Name}" title="{!eve.Name}"/>
                            </p>
                            <p class="slds-tile__title slds-truncate"> 
                                <apex:outputField label="Gender" value="{!eve.Gender__c}" title="{!eve.Gender__c}"/>

                            </p> 
                        </div>
                            </div>
                    </li>
                    <apex:inlineEditSupport event="ondblClick" showOnEdit="saveButton,cancelButton" hideOnEdit="editButton" />
                </apex:repeat>
            </ul>
            <apex:pageBlockButtons >
                        <apex:commandButton value="Edit" action="{!save}" id="editButton" />
                        <apex:commandButton value="Save" action="{!save}" id="saveButton" />
                        <apex:commandButton value="Cancel" action="{!cancel}" id="cancelButton" />
                        <apex:commandButton value="add row" action="{!addRowToTable}" id="addRowButton" reRender="data0" />
                    </apex:pageBlockButtons>
        </apex:pageBlock>
        
    </apex:form>
</div>
</apex:page>
