Here’s a simple update to spice up your option sets: add color! In our example, we will be applying color on an option set for Appointment Type, but you can follow these steps for any option set field in your system. For now, you’ll need to use the Classic Solution Designer if you’re an Online Customer to apply color.

Apply Color on Option Set Values

1. Open the Option Set (from the Classic Solution Designer).

2. Within your Option set, click on one Option. Update the value in the Color field (highlighted below).

In an Option Set field, select your option and update color

3. Repeat for all values until each has a unique Color.

Select Calendar Control then click the Add button:

Adding Calendar Control to our view.

Back at the Custom Controls box for this view, we have to define where this control should run. In this example, I want to use it regardless of access type. Below, I have to set Start Date & Description on my control. This is how the system knows when to display which Activity on which date and the text that appears on my calendar. Here, I have set Start Date to be my Scheduled Start and Description is my Subject field. When you have finished, click OK.

Select where this control should run and map Start Date & Description.

Here’s where the color comes into play!

Click the arrow next to Color to map to our color option set details we configured above.
