'How can I give Bootstrap select a normal height if there is nothing selected?

I am using bootstrap select in my page and I need it to be empty by default (and value="") when the page loads (it is a required field so when the user submits the form, the validation message will appear in case it's empty).

It actually works but it looks weird/odd/too flat:

And this would be the desired result:

I have used this attribute to make the select look empty: data-none-selected-text="" and it actually looks empty but too flat.

If I remove that attribute, I'll get this Nothing selected placeholder which I don't want:

How can I make the design consistent and keep the same size whether something is selected or not?

If you really don't want to use placeholder text, just use a blank HTML space (&nbsp;) as the data-none-selected-text or placeholder attribute value. Either approach results in the select box holding a standard height with no visible text in it.
