EXT ComboBox drop-down box width does not match the control width

Today, we use ComboBox in ext to find that if you set the width of ComboBox too small, the width of the drop-down box in ext may exceed the width of your ComboBox, in fact, you only need to set the width of the drop-down box in ComboBox expand.

 

CodeAs follows:

 

Code
{
Xtype: " Combo " ,< P>

width: 36 ,

listeners :{< br> Expand: function () {
This . list. setwidth ( This . width);
}< BR >}< br>
