I'm designing a product-based website, and I have a dropdown selector at the bottom of one of the pages near the footer. When I went to review development, I noticed that the way the dropdown selector was coded, the menu options expanded on top of the field instead of below (see attached). I assume the developer did this so that the menu options don't cover up information in the footer when expanded, but was concerned with the break in convention for this pattern.
I'd like to recommend the developer change this, so the menu options expand below the field like a traditional dropdown menu, even if they cover some information in the footer. I think this is okay because the dropdown menu is the user's focus once it's expanded, and once they've clicked into the dropdown menu the footer content is not relevant to the decision they're making (selecting an option).
Are there usability concerns with the current solution (attached) and am I making too big a deal of something that's pretty minor in the scheme of things? Is it okay to break this pattern a bit in order to not obscure information in the footer?
Thanks for the help.
