Hi naresh,
the idea in the vertical JCarousel is this - you multiply the number of the items that you want visible by the height that's required for one item to be fully visible (depending on the settings you have enabled in the administration panel - short description, details button etc.) + around 5-10 pixels per item (you should play around with this value until it looks good to you). So in your particular situation, where you want to have 5 products and with only "item name" and "product prices" enabled, the item should have minimum height of 190px (this height is automatically generated and you should play around with the JCarousel to find it out) .
So you do this:
190px+5px multiplied by 5 items equal to 975px . This value of 975px should be applied to
.nop-jcarousel .jcarousel-clip-vertical{
height: 975px;
}
If you need anymore help, please let us know.
