Hi @siang7711,
You will need to use CSS to accomplish this. This falls under custom development work and is outside the support of our free plugin. I recommend raising this kind of question in the general WordPress forums in regards to using CSS.
Alternatively, users of the pro version of the plugin I can provide support for this kind of thing as it is a small customisation.
Thanks,
Thanks for getting back! I had fixed the alignment issue.
I face another problem here. The drop-down selection text, is it possible to change to black instead of transparent/white?
