Hi,

Going to explain this carefully as I have seen forum posts where people are confused and give the wrong answer.

A drop down / combobox. This is one with the <select> html tag.

When there are items in it and you click on it, you see all the items in a drop down.

Clicking gives focus.

If i were to use the keyboard to TAB from a another control to the dropdownbox. How via javascript could I open the drop down to show all the selectable items as if the user clicked on the combobox with a mouse.

thanks

@hosneylk: thanks for posting that, however, while it reads like it is what I am looking for. The end result html does not work. The box doesn't open on focus.
Tried this in IE8 and FF3.5.
