You can do such design with HikaShop since it also supports bootstrap.
However, on Joomla 2.5, and if your template is not compatible with bootstrap (which is the case with the template of our demo website), you can't activate the bootstrap compatibility in HikaShop.
Upgrade your demo site to Joomla 3.1 and bootstrap will get more customers HikaShop.
Мust demonstrate a competitive advantage Hikashop, for example, the filter (now no demo).
Yes, that's something we want to do but it will take months before we can do it as it is a lot of work.
We're currently working on migrating our own website, which is still on 1.5, to Joomla 3.1
