ExtJS - ComboBox width in EditorGridPanel

Question

I have set up an EditorGridPanel with ComboBox's and it's working well. The only issue I'm having is that the width of the ComboBox seems to only expand to the width of the grid column, and not the content of the ComboBox itself.

Is there a way around this?

Here's an example of what I mean:

Thanks!

Answer 1

Use the

listWidth : Number

config option

You could calculate the length of the largest content element and then set the listWidth in the 'expand' event of the combo

Cheers!

Answer 2

listWidth does'nt exist in extjs 4.

Add below to combobox config:

matchFieldWidth: false,
listConfig: {
    width: 200
},
