Virtuemart - plus and minus button disable

[szilagyia]

Hi!

How to do it to the customer to manually enter the product quantity in the VirtueMart (plus and minus button disable)
I use VirtueMart 3.0.12 (themler template) and Joomla 3.4.8

Thanks

or over ride the
templates\TEMPLATE\html\com_virtuemart\sublayouts\addtocartbar.php  and leave out the buttons
