Our website uses the excellent 'Relevanssi' plugin for WordPress search, and we need the front-end search form created. We have already made a mockup of what we want the finished form to look like (dropdown options shown below field).
The search form needs to search all by default, and be able to then search only by Magazine (= a custom taxonomy), by TV (all posts that have post format = video selected), by Podcast (all posts that have post format = audio selected) and by News & Events (all 'posts').
Here is a link to the dev docs for the plugin: [url removed, login to view]
There are posts on there that show you how to query posts based on taxonomy, tag and custom post types and custom formats.
Any questions, please ask. Need work done ASAP!
Note: Your job is just to create the search form itself and place it into the header of our website in place of the current form and over the top of the Revolution Slider video on the home page. The finished result must look like the search form in the attached mockup (excluding the background image, titles and logo), and it must be responsive.
