how to adjust extjs combo box width

Question

I have a panel which has a couple of combo box and buttons. The first combo box is aligned to the left. I want to align that similar to those below. The button should also be adjacent to the combo. Please help. Below is the code

filterPanel = new Ext.Panel({
        renderTo: document.body,
        bodyStyle: 'padding-top: 6px;',
        title: 'Filters',
        collapsible: true,
        collapsed: true,
        width: 450,
        frame: true,
        floating: true,
        layout: 'form',
        labelWidth: 150,
        buttonAlign: 'center',

        items: [
            {
                layout:'column',
                items:[
                {
                    columnWidth:.9 ,
                    layout: 'form',
                    items: [{
                        xtype:'combo',
                        id: 'xFilterEmail',
                        width: 250,
                        listWidth: 200,
                        fieldLabel: 'Filter by Owner',

Well... the first combobox has a width of 250. Did you try to make it equal to the others (200) ? And if you can't manage to move the button to the left, i would do it with CSS instead. If you give the button an ID "myButton", the following CSS should do the trick:

#myButton .x-btn {
    margin-left:-20px !important;
}

And don't be afraid to edit ExtJS classes, cuz it will make the changes to this button only. I do this all the time and results are as expected.
