I don't even see a property on the combobox control to set the height of the combobox items!

here's the offending combobox...

ExtJsComboBox4 = new Ext.form.ComboBox(
{
displayField:'stuff',
listWidth:0,
mode:'local',
store:[['mon'],['tue'],['wed']],
inlineStore:[
'mon',
'tue',
'wed'
],
valueField:'myid',
id:'ExtJsComboBox4',
applyTo:'ExtJsComboBox4',
width:130,
height:24
})

any ideas?
thanks!
