Hi, i need some guideline about building a website like http://perfectpizza.co.uk/
particularly, m interested in the ordering system at this URL :
i want to know, that is there any CMS (opensource like joomla, os commerce etc..) that can just provide exact cataloge with effects. or should i custome built the website CMS.
also, from where i can get these effects (like opening the choices lists upon selection of any item etc..)
also, the Perfect Price Promise functionality.(i think that would have to be developed by myself)
so pls guide me.
thanking in anticipation.
