when i create placeholder link in any inside level of the menu JoomSef creates a link
www.iota-tax.org/undefined instead of no link at all

can i avoide / fix /hack this problem?

any one had the same?

Hi,

I guess this is more swmenu than JoomSEF problem. If it generates an link (a element) to a separator/placeholer, this sounds a bit weird to me.
JoomSEF tries to convert any link generated via sefRelToAbs function. I recommend hacking swmenu and removing generation of a link for it.
