[Plugin: Custom Field Template] How to repeat the Fieldsets?

I need to repeat 4 informations in a page with a fieldset like this :

[Caractdespieces]
type = fieldset_open
multiple = true
multipleButton = true

[Niveau]
type = textfield
size = 35
blank = true
class = Niveau
blank = true

[Piece]
type = textfield
size = 35
blank = true
class = Piece
blank = true

[Dimensions]
type = textfield
size = 35
blank = true
class = Dimensions
blank = true

[Revetement de sol]
type = textfield
size = 35
blank = true
class = Revetement de sol
blank = true

[Caractdespieces]
type = fieldset_close

And that will look like this : Screenshot

Well, I know that I can insert this code : <?php getCustomField('Niveau'); ?>, etc.

But, this is what I need : The fieldset has to repeat itself with the good information. And I need to find all the fieldsets I used in admin panel into my page. ( Like the first image )

I think we need to use a script, but I don’t know how to create it. I searched on the forum, but I didn’t found anything to help me.

Well, I hope you may help me.
