Dear longvu76,
We only design and override theme for Virtuemart on specific template so that using virtuemart theme of JA Orisite on JA Lens template is not suitable, they are different templates with different themes. If you don’t wanna use default virtuemart theme, you need a little bit heavy customization for JA Lens template.
All of overridden files/folders of JA Orisite theme for virtuemart locates in JA Orisite template folder, for example:
– Override CSS for blue theme: ja_orisitethemesbluecssvmsite.css (the same with other theme)
– Override category, cart, product page structure: ja_orisitehtmlcom_virtuemart
Regards.
