Graphic design/change of extended filter option

Hello,
I’d like to change position and size of SELECT button. I’d like it to have it in same size as other text (F.e. field CHECK keeps same font and size of the text, but SELECT field is significantly bigger than the text – see attached print screen.). Also, I’d like to have the SELECT field next to the text, not under. Is it possible to adjust it somewhere please?
My SELECT button is yes/no option, so it doenst make sense to use another type of field.

Is it also possible to somewhere change in general the font, background color and font size?

Thank you,
Tomas
