Thank you for your kind words 🙂
1. I think so, this custom CSS should help you out:
[html]div.asp_sb.searchsettings form fieldset.asp_custom_f {
margin-top: 0 !important;
}
.asp_custom_f .chosen-container .chosen-single {
line-height: 44px !important;
min-height: 55px !important;
}[/html]
It should look like this afterwards: https://i.imgur.com/T0NxIKZ.png
You might have to adjust it here and there, but it should be a good start.
2. Yes, by adding this empty option line to the field like so: https://i.imgur.com/2uSvNbq.png
It’s a fairly new feature, it is yet missing from the documentation, sorry about that.
I hope this helps!
