Hi Michelle,

Although ExtJS code in general can be set to use a blank like in the following example here:

I'm not certain how we'd be able to render it properly within the Survey Editor. You can use a   as a value so the dropdown appears with a blank, but without something to swap out the   with an actual empty value upon selection, you will literally see " " as the selected option.

Regarding the likert scale, I haven't found any examples of ExtJS being able to pull this off (I've seen HTML ones only). However, I will confirm with our developers whether if a Likert scale is possible or not and whether a proper blank combobox solution.

Regards,

Jon
