Detailed description:

Form control with "combobox" role has no associated label
Each form control must have an associate

What to do:

• Add a for attribute to a visible label with the id of this control (e.g. );
• OR put the UI element inside a visible element;
• OR add an aria-labelledby attribute to the control. It must point to visible text on the page that is meaningful as a label;
• OR only if the design cannot have a visible label, use the title attribute to provide a label.

Why is this important?

Associating a meaningful label with every UI control allows the browser and assistive technology to expose and announce the control to a user. Associating a visible label also provides a larger clickable area.
