Anatomy
Header

Section
The Section component represents a section within a Hopper container.
Composed Components
A ComboBox uses the following components:
Usage
Disabled
A combo box in a disabled state shows that it exists, but is not available in that circumstance. This can be used to maintain layout continuity and communicate that a field may become available later.
Disabled Item
A combo box with a disabled item.
Error
A combo box can be displayed in an error state to indicate that the selection is invalid.
Sizes
A combo box has multiple sizes to choose from. The combo box option also changes size based on the size of the combo box.
Labeling
If a visible label isn't specified, an aria-label must be provided to the combo box for accessibility. If the field is labeled by a separate element, an aria-labelledby prop must be provided using the ID of the labeling element instead.
Icon Prefix
An icon can be displayed at the start of the select trigger.
Text Prefix
A short text can be displayed at the start of the select trigger.
Fluid
A combo box can take the width of its container.
Controlled
A combo box can have a controlled selected value. In this example, it shows how it is possible to deselect an option.
Custom Filtering
A combo box can overridde the default useFilter function from RAC. This can be overridden using the defaultFilter prop, or by using the items prop to control the filtered list. When items is provided rather than defaultItems, combo box does no filtering of its own.
Allow Empty Collection
A combo box can be rendered with an empty collection. If you want the popover to open with a custom message, you can use the renderEmptyState prop within the listBoxProps prop.
Allow Custom Value
A combo box can allow the user to enter a custom value that does not match the list.
Form
A combo box can be part of a form. To submit the value of a combo box, make sure you specify the name property.

A combo box can have a menu that automatically adjusts its width based on the longest item.
Menu placement
A combo box's menu can have a customized menu placement using the direction and align props.
