This is regarding an Inventory Staus Grid page that displays inventory according to the date entered by the user. The user uses a tab key to move the focus to the ' Vehicle number' column and again using the tab/down keys move focus to a particular vehicle number.Upon clicking F5, a 'Vehicle Specifications' div gets open.Now again if the user uses the tab key to move focus onto a different vehicle number, clicks F5, then a second Vehicle Specifications div gets open, which is wrong. I want that at a time, only one vehicle specifications div must be open.
So i have to do this - disable the tab from giving focus to the table if a div is already open. How?
