Make field content as exposed filter dropdown I have a field in my node like brand, where in admin enters the brand name and creates the node. I want to make a exposed filter out of this as a dropdown with all the data entered by the admin. How do i do it ?
your question isn't 100% clear but it sounds like you want to display the nodes in a view and want to filter them with an exposed "brand" dropdown? 
I also assume your "brand" field is a term reference to a vocabulary.

Create a view for the nodes and add a filter for "Content: Has taxonomy term" and select your "brand" vocabulary, "dropdown" as the filter type and "expose this filter".
