Category List Outside Of Full Calendar View

Is it possible to create a select element with each option populating all current categories? (And also filter out unwanted categories as well.)

Basically I’d like to have a dropdown which will show every needed category. Then depending on which category is selected, a short feed of upcoming events for that category will show/refresh below it.

This is all trying to be accomplished on an interior page template, separate from the EM template pages. Right now I have a list of categories with their link, and also showing their category ID using:

<?php echo do_shortcode( '<ul>[categories_list hide_empty=0 exclude=22]<li>#_CATEGORYLINK, #_CATEGORYID</li>[/categories_list]</ul>' ); ?>

Any help is greatly appreciated!
