List Box defaults to display two lines. Any way to increase to 3?

Our registration form is working but has a display annoyance.

Our list boxes are all 2 lines high (while actually having up to six selections in the list box.  I'd like to see what 3 lines would look like yet still retain the scroll command arrows to the right.  I've looked at the Custom Field and the Global configuration and not finding a way to change this to 3 (or other) lines.  Is there an easy way to modify this?

Thank you,

Hi Bruce

Edit the custom field, change Size parameter to the value you want (3 in this case) and it should work as expected

Hello,  
I tried this with several different values (and saved them) and did not notice any change.  

Any other thoughts?
Thank you,

I will say that currently "Css Class" is blank.  Should there be something in that box?
(As I tried size 3, 4, 5, etc with no effect)
Thank you,

Hi Bruce

CSS Class is not needed here. For this, I will also need to check it directly on your site when I received your ticket. Please remember to send me link to the page which I can see this issue

Tuan logged in and noticed that
"it was caused by wrong Twitter Bootstrap version configuration. I (Tuan) changed Events Booking to use Twitter Bootstrap 5 (for our installation) and updated code of the extension a bit."

Now, two things: the default display is quite reasonable and shows about 3.5 lines of choices of our 6 in the list selector.  Plus, when I select size 3 or 4 in the Custom Field controls, they work exactly like they should.
So this was a big help for us and looks good now!
