State

• options = []: An array of all options. The options can be strings or objects.

• value = []: The current value of the component: this will be a subset of options.

• placeholder = '': The placeholder label to display.

• match: This function should return true or false for every option to determine whether the item should be visible or not. By default, it does case-insensitive fuzzy filtering. For example, "js" would match "JavaScript".

• focused = false: The current focused state of the component

• renderer: This function is used to render each individual option. By default, it underlines the parts of the text that match the fuzzy filter.

• val =str: This function returns the value of an option. If your options are an array of objects, this is used by the default matching function and to determine the label to display for each option. For example:

{ options: [ { firstname: 'John', lastname: 'Smith' } , { firstname: 'Jane', lastname: 'Smith' } , { firstname: 'Jack', lastname: 'Smith' } ] , val: d => d.firstname + ' ' + d.lastname }

* **`suggestion`**: The index of the currently suggested option. This is used internally, you will rarely set this.

* **`query = ''`**: The text currently entered into the textfield
