Changing the size of a select list(custom field)

[gajdi]

Hello!

I've already used this forum countless times, and I always found what I was looking for.

I'm using Joomla! 2.5.6 and VM 2.0.8e

I wasted half of my day while I was looking for the file to change the generate HTML code for the product page.

So I have a site, on which I want to sell computers.
There are some custom fields (cpu,ram,etc.)
These are dropdown "select" menus, but only 1 option is visible.
I'm looking for a solution, where I can make 4-5 option visible.
I've already tried css styling (height:5em;), yet it was not useful, it only made the only option field taller.

Thank You for any ideas
