thanks so much "Hero" and "Mwen"
for post
(i post my issues here after many days of attempts to solve , by myself

)
And about
the
docs i checked are:
browse_1
template.css
theme.css
productlisttable.tpl.php
In the template.css (css style of the joomla template,virtuemart themes.css ,etc.. )
and as posted before in the picture...
no code for table and cells dimensions and layout found....
only row code about padding ....
But yess : the template.css doc change the layout of product list using :width , padding, height , <br>, border , etc...
But: only with option like: "div no table" , etc.... , it don't work with :"fixed 1 product per row".
But as just said : if a product don't have the price published ,
the layout
(product name,image,product short description,etc..) appear as a "drunk dog " (never seen a drunk dog?....

)
then the only way for get a stable layout in the list of products is set the virtuemart with: "fixed 1 product per row" ..
(all products manufacturer and category list have to appear under a table layout)
sorry for my limits but after days and days of searching , "try & error" , etc.. ,
the :"fixed 1 product per row" , it's the only one decent solution i found.
(i know that are fiew code rows for get that i'm looking for but where i have to place ? )
About manuals i checked and rechecked several times .....
found helps for other issues but nothing about :
where and how change the "dam......d" product list table code....
nobody have found wich doc include the table code used by virtuemart for the "fixed 1 product per row" option?
any help it's wellcome
thanks in advance
