Interface always comes first

totlechao3

Start date: <input type = "text" name = "start_rq" size = "10">
<img src = "img / calendar.gif" onclick = "Calendar.display ('start_rq')">
------------------
Click on the image (calendar.gif), execute js, a small interface for selecting the date will pop up, but there is a drop-down box blocking half of the date interface. The interface is always on the front and will not be blocked? Thank you very much!

Set z-index to a large value, such as 999

If it is <select>, <input> these elements are blocked, it is a bit troublesome to solve.

Where is z-index set? Is that so?
<img src = "img / calendar.gif" onclick = "Calendar.display ('start_rq')" z-index = "999">

Set to:
<img src = "img / calendar.gif" onclick = "Calendar.display ('start_rq')" z-index = "999">
Or not.
