 HOW TO USE

 Create a Button looking like this:

 <a href='{{ route('modal.show', 'user') }}' data-toggle="modal"  data-target="#createModal" data-select='assigned_to' class="btn btn-sm btn-primary">New</a>

 If you don't have access to Blade commands (like {{ and }}, etc), you can hard-code a URL as the 'href'

 data-toggle="modal" - required for Bootstrap Modals
 data-target="#createModal" - fixed ID for the modal, do not change
 data-select="assigned_to" - What is the *ID* of the select-dropdown that you're going to be adding to, if the modal-create was a success? Be on the lookout for duplicate ID's, it will confuse this library!
 class="btn btn-sm btn-primary" - makes it look button-ey, feel free to change :)
 
 If you want to pass additional variables to the modal (In the Category Create one, for example, you can pass category_id), you can encode them as URL variables in the href
