Add filter on the schedule

Scheduler Javascript
#1

I add a filter on the schedule. I select one option on a same working day.

The example of filter is used the < checkbox > to select the option. Now I want to ask I may use the < combo box > or not ? And if yes, how about the method of code ?

Thanks !


<div class="filters_wrapper" id="filters_wrapper">
			<span>Display:</span>
			<label>
				<input type="checkbox" name="appointment" />
				Appointments
			</label>
			<label>
				<input type="checkbox" name="task" />
				Tasks
			</label>
			<label>
				<input type="checkbox" name="training" />
				Trainings
			</label>
