At the moment, when a learner clicks on the button Browse Courses by Institution on the OL Homepage, courses are only searchable under one topic category.  In my case, my courses are listed under the topic, Languages and Communication.  However, the content content is relevant to other categories such as Education, Self Improvement and Humanities etc.  I would like to be able to select multiple topics, which are relevant to my course content, in order to help the learner find what they are looking for.  It would improve the chances of learners identifying relevant courses for them.
