Mininmum? shorten?
You mean maximum and shorten i suppose?
in that case you can add to almost every template tag a length parameter to limit the text displayed, like
{$title, length=120}
which displays max. 120 chars
As Basti said you can use lenght tag, but you dont need to worry about this.
Into search results if title is already too big Google automaticly truncates the text.
So even if user title is " BEST " = 4 characters, into details page will be {$title} - {$list_name}
Hope this helps
Nope the javascript error doesnt have such message. The error message is coming from our php validation functions.
Do you have custom plugins? Looks like a plugin is applied to check for title length
