I am trying to customize default liferay navigation .
In default liferay navigatin the child menu appear on mouse hover but i try to do this on-muuse click.
mean the child menu will appear when I click on the menu.

How can I do this???

Not easily. The child menu is a hidden div that has it's visibility toggled when the parent is hovered.

What you're asking to do would now involve CSS changes and javascript support. The CSS changes would remove the :hover from the parent element to stop the automatic stuff. The javascript changes would require adding click event handlers on the parent element in order to manually toggle the child menu.

can you please share any code??

No, because I've never needed to do such a thing.
