How to Hover over and click on an invisible element using selenium webdriver?

Question

There is an invisible element on my HTML page which becomes visible when a mouse hover is done on the element. What I Have to do is

1. Hover over the element
<

Answer 1

My case we had a table of rows, if mouse over on the row, one of the column(td) should display some 4 icons, we should click on it.

Action action=new Action(driver);
action.moveToElement(hoverElt).clickAndHold().build().perform();

It worked for me. moveToELement() move your control to the element

clickAndHold() clicks and holds the hovered element, so that its easy for us to do operation on visible elements.
