I am using PrimeFaces 5.1 in my application,I used selectOneMenu inside of dataTable, When I press on add more button to need to focus selectOneMenu button.

Sample Code

JavaScript

function focusMenu(id)
{
var focusId="#{p:component('mainTable')}"+":"+id;
PrimeFaces.focus(final);
}

xhtml

<div style="padding-left:4px;height: 
expression(this.scrollHeight > 399? '400px' : 'auto');max-height:400px;overflow-x:auto;overflow-y:auto;">  
<p:dataTable id="mainTable" value=#{main.UserDataTable} .....>
<p:column headerText="Drop Down">
<p:selectOneMenu id="dropdDownId"...>
.....
</p:selectOneMenu>
</p:column>
<p:column headerText="Operation">
<p:commandButton value="Add More Row" action="{user.addMoreRowAction}"
update="mainTable"/>
</p:column>
</p:dataTable>
</div>

Java

public String addMoreRowAction()
{
RequestContext.getCurrentInstance().execute("focusMenu('"+ rowIndex + ":dropdDownId"')");
return null;
}

Here the above code is work fine to focus the last added selectOneMenu as what I expected, but the browser scroll bar is not move down based on focusing the recently added selectOneMenu component.

Please help me to solve the issue.

You can take the scrollbar to the focus id using scrollTop function. Pass the focusid into the function.

function setScrollPos(focusId){
    $('html,body').animate({
             scrollTop: $(focusId).offset().top-65
    }, 1000);
}

Call the above function

function focusMenu(id)
{
var focusId="#{p:component('mainTable')}"+":"+id;
PrimeFaces.focus(final);
setScrollPos(focusId); <<------
}
