I would recommend using Google Search to set-up your own customized search feature for your website. The instructions are very straight forward and easy to accomplish. Google allows you to customize and set the the search for either your site and/or the internet.
Plus, you have the option of adding Adsense (and earn a few extra dollars) if you create a separate web page on your site to display the search results.
Once you have customized the Google search features, you simply copy and paste the code provided where you want the search boxes to appear on your site.
For the convenience of visitors to this site, if you take a look at each web page on this site you can see that I have an average of two Google search boxes on every page. There is a small Google search box in the upper right hand corner of every page as well as a larger search box at the end of each page.
I have chosen the settings in the Google search box set-up options to have the search results displayed on a separate page on the site that I built for this purpose. (Google provides very helpful instructions on how to do this as well.)
Here is a link to Google's Introduction to Customizing a Search feature to use on websites:

As for the part of your question about how to create a drop-down box for the search function, I have to confess that level of coding is far beyond my understanding so I can't help you with that one.
I particularly like this HTML resource when I need to learn how to code something new:

There are many excellent HTML help forums that have the coding expertise to answer that part of your question. I'm sure that Intuit has a forum where you can get help with the drop-down option or this site has an excellent webmaster help forum as well:

I hope that helps!

P.S. When you get an answer to how to create a drop down box, it would be great if you came back and posted that answer here!
