HM_PG_ChildPerCentOver

Description

Sets the horizontal distance a child menu overlaps its parent menu, as a percentage of the parent menu's width. That is, if the parent menu is 120 pixels wide and HM_PG_ChildPerCentOver is given a value of 25, then the child overlap will be 25% of 120, which is 30. All menu trees in the page are affected.

HM_PG_ChildPerCentOver overrides HM_PG_ChildOverlap parameter and the site-wide global settings declared in the external script.

Comments

If you do not want your child menus to overlap the parent menu, give HM_PG_ChildPerCentOver a value of 0.

To leave space between your child menus and their parents, give HM_PG_ChildPerCentOver a negative value (ex: HM_PG_ChildPerCentOver = -20. This would place your child menu away from the parent at a pixel distance of 20% of the parent's width.)
