Styling compatibility issues with Avada theme

Hi there,
I’m having a few styling issues with the advanced search options – I’m using the Avada theme.

1. When ‘customise search’ button is clicked (to make advanced search appear) the grey dropdown box (container div?) isn’t properly formatted to be 100% of the width. This leaves a little white gap on LHS just short of the full width on the page.

2. On the advanced search dropdown (front end), each new line is being shown with a bullet point left aligned on the same line, while the actual advanced options themselves vary in their alignment e.g. dropdown selector for categories is centre aligned, radio buttons for distance selection left aligned (over bullet points), text boxes for special offer left aligned (and sometimes appears layered underneath the bullet point) All headings for each advanced search option are centre aligned.

How can i solve items 1 & 2 above – to get rid of the bullet points and left align everything within the advanced search? And then ensure the entire container is properly styled?

Thanks in advance for any help you can give.
