So default behavior for a select field on an android device is to show approx 3 items of data. In chrome, the browser displays 10-20 as a modal overlay.

which CSS rules do i need to change to modify the number of items in a select field?

Also, are there other stylings for select fields, the default touch implementation is pretty ugly with the whole Done/Cancel buttons on the bottom of the display.

thanks

PHP Code:
   items: [
        {
        
xtype'selectfield',
        
name 'room_letter',
        
label'Room',
        
valueField'room_letter',
        
displayField'room_letter',
        
storeRoomLetterStore
            
//useClearIcon: true,
            //autoCapitalize : false
        
}, {
