jsf align checkboxes in panelgrid - html

Question

Hello I have a form that is rendered with a panelgrid with 3 columns like this:
Label-InputField-ErrorMessage
I want to add some checkboxes but I have trouble with the alignment.
<h:panelGrid columns="3">
<h:outputText value="Όνομα:"></h:outputText>
<h:inputText id="name" value="#{regBean.name}" required="true"
requiredMessage="Παρακαλώ εισάγετε όνομα!"
>
<f:validator validatorId="nameValidator" />
</h:inputText>
<h:message id="namemsg" for="name" style="color:red"></h:message>
<h:outputText value="Επώνυμο:"></h:outputText>
<h:inputText id="surname" value="#{regBean.surname}" required="true"
requiredMessage="Παρακαλώ εισάγετε επώνυμο"
>
<f:validator validatorId="nameValidator" />
</h:inputText>
<h:message for="surname" style="color:red"></h:message>
<h:outputText value="Ενδιφέρομαι για"></h:outputText>
<h:selectManyCheckbox>
<f:selectItem itemValue="1" itemLabel="Number1 - 1" />
<f:selectItem itemValue="2" itemLabel="Number1 - 2" />
<f:selectItem itemValue="3" itemLabel="Number1 - 3" />
<f:selectItem itemValue="4" itemLabel="Number1 - 4" />
</h:selectManyCheckbox>
<h:commandButton type="submit" value="Submit"></h:commandButton>
<h:commandButton type="reset" value="Reset"></h:commandButton>
</h:panelGrid>
Without selectboxes:
This is what I get when I add them:
I want something like this:
I tried adding html tags inside the h:panelGrid but it failed. Is there any way to achieve it only with css/html/jsf?
Thx in advnace

It was easier than I thought. I had to add layout="pageDirection" at the <h:selectManyCheckbox> and wrap the selections in a panelGroup
The fixed code:
<h:outputText value="Ενδιαφέρομαι για"></h:outputText>
<h:panelGroup layout="block">
<h:selectManyCheckbox layout="pageDirection">
<f:selectItem itemValue="1" itemLabel="Item 1" />
<f:selectItem itemValue="2" itemLabel="Item 2" />
<f:selectItem itemValue="3" itemLabel="Item 3" />
<f:selectItem itemValue="4" itemLabel="Item 4" />
</h:selectManyCheckbox>
</h:panelGroup>
