combo excell wider than column size

Is it possible to define the width of combo(dropdown list)excell in grid to be wider than columnsize?

for example
mygrid.setInitWidths(“100”);
var combo = mygrid.getColumnCombo(0);
combo.setOptionWidth(999);

i’m try above but combo still width 100.

Try to use following code to set options width:

mygrid.attachEvent("onEditCell",function(stage,id,index){ if(stage==1&&index==COLUMN_INDEX){ var c = mygrid.getColumnCombo(0); c.setOptionWidth(999) } return true })
