We have many sites all on separate domains but all share some common components. One component is a "Search Box" at the top of each home page that allows you to search for holidays.
The search box is a <form> with a bunch of <input>, <select> <label> and <ul> tags. The labels, dropdowns, inputs all have the same default values across each site.
Question: will the search box been seen as duplicate content when indexed by Google?
