Primefaces popup dialog not working - jsf-2

Question

I have a jsf page having a popup button that opens a following dialog popup:
</h:form>
<p:dialog id="dialog" header="Select different user"
widgetVar="dlg" appendToBody="true">
<h:form id="form23">
<h:panelGrid columns="2" cellpadding="5">
<h:outputLabel for="username" value="Username:" />
<p:inputText value="#{loginBean.username}"
id="username" required="true" label="username" />
<h:outputLabel for="password" value="Password:" />
<h:inputSecret value="#{loginBean.password}"
id="password" required="true" label="password" />
<f:facet name="footer">
<p:commandButton id="loginButton" value="Login" />
</f:facet>
</h:panelGrid>
</h:form>
</h:form>
But instead of opening as popup it is getting displayed outside the page itself. the dialog is outside the main form. Help!!
I tried that but still the same problem persists..below is my modified code..
<h:form id="create-ticket">
<p:dialog id="dialog" header="Select different user" widgetVar="dlg" appendToBody="true">
<h:panelGrid columns="2" cellpadding="5">
<h:outputLabel for="username" value="Username:" />
<p:inputText value="#{loginBean.username}"
id="username" required="true" label="username" />
<h:outputLabel for="password" value="Password:" />
<h:inputSecret value="#{loginBean.password}"
id="password" required="true" label="password" />
<f:facet name="footer">
<p:commandButton id="loginButton" value="Login"
/>
</f:facet>
</h:panelGrid>
</p:dialog>
<h:panelGroup>
<h:outputLabel value="#{I18N['Create_Ticket_for_other_users']}" styleClass="atf-header"></h:outputLabel>
</h:panelGroup>
<h:panelGroup id="search_section" layout="block"
styleClass="atf-content-area atf-separarot-botton"> <!-- This is the section where we get the grey background -->
<h:panelGroup id="input_search_section" styleClass="">
<h:outputText id="name" value="Siddharth Mishra"
labelStyleClass="atf-label">
</h:outputText>
</h:panelGroup>
<h:panelGroup styleClass="atf-right atf-inline-block">
<p:commandButton id="btn_search" value="select different user"
styleClass="atf-button-search" onclick="dlg.show();" type="button"
>
</p:commandButton>
</h:panelGroup>
</h:panelGroup>
Now i only have one form you can see the popup dialog section + the button which is calling the popup under h:panelgroup.Atached is the image how the form currently looks Thanks in advance

You need to restructure your code.
*Don't nest forms inside other forms.
*You dont have the end-tag of your p:dialog.
<h:form>
<p:dialog id="dialog" header="Select different user"
widgetVar="dlg" appendToBody="true">
//Content ex inputtext
</p:dialog>
<p:commandButton value="Show Dialog" onclick="dlg.show();" type="button" />
</h:form>
