Form fields have a required name property, so that's the only property you have to pass to Select to start using it. If you need to handle its change events - add an onChange property to it.
Same as when using native inputs in React, Select can be used as a controlled or uncontrolled component. By default, Select is uncontrolled and lets you define its default value using the defaultValue property. In this case, all change events are handled automatically. This approach is helpful when you're populating the field default value from a data source, but you don't need to control it manually afterward.
If you need to control the state of the field manually, you can use the value property. That will give you complete control of the component value and will stop handling the value automatically. You will have to update the state using the onChange handler and will be able to add custom logic before that happens.
You can use hasError property to show the user that Select is not passing the form validation.
Select can be disabled with the disabled flag. Remember that disabling the field will remove it from the form submit query.
Select supports a content slot on the left side, which you can use for displaying text or other components.
For consistent Icon usage in text fields, you can use the icon property instead of startSlot and pass the icon SVG component.
To let the user know what data you expect them to type in, add labels or status messages to your fields with the help of the FormControl utility. Adding a placeholder should help even further by defining the field's data format.
Note: Don't use placeholders as labels for the fields as users won't see the placeholder when input contains a value.
