Hi All,

In our application we have combo boxes implementated using tables with fixed column width(fixed combo width).
and newly i have added a functionality for these combo box.
functionality is expand combo box on rightclick (using oncontextmenu) to fit to lengthy text.

oncontextmenu=function_call(object);

inside function:
obj.style.width="auto"

but the problem i am facing is, i have multiple combo boxes in row, so if i expand these combo box on right click , windo width is also adjusted accordingly i.e screen width is expanding.
Inturn i want to keep rest objects untouched and want to expand only the selected combobox and selected combo box must overlap adjecent combo, not expand the window size basiccaly.

let me know how can i achive this?

    <div id='box3' onclick="this.style.zIndex=zzTop++"></div>
  </body>

Click on a box to see this simple example work. Changing the width of a 'position:absolute' element increases or decreases the overlap.

Set the basic zindex for combobox in your divs and use the javascript function to swapping the depth of zindex to the highest value while using your context menu.

I used position:absolute and zIndex in my implementation.It is working fine as expected.

Thanks you so much.
