customizedInput/customizedOptions Advanced configuration
Regards the custom implementations, they're targeting the two main component of this plugin, which is: InputComponent, OptionsComponent (The result)
For that you've two classes exported to help you manage correctly extending with your own classes
The Defaults implements these interfaces:
The IInputComponent interface can be defined as:
export interface IInputComponent {
/**
* Input component template string
* @default `<input />`
*/
render():string;
/**
* onInputChange event handler
* @param inputElement - HTMLInputElement
* @param value - input text value
*/
onInputChange?(inputElement:HTMLInputElement, value:string);
}
The IOptionsComponent interface can be defined as:
export interface IOptionsComponent {
/**
* The list element tag selector
* This value can be a tag string `ul` `div` `ol` that indicates tag name,
* or it can be a class selector (or id selector) `.myClass`/`#myId` which is
* returned in @render method template
* @default `ul`
*/
listElementSelector:string;
/**
* Options component template string
* @default `<ul></ul>` base list tag
*/
render():string;
/**
* Option row template string in Options component
* @param option
* @default `<li> ${value} </li>`
* @requires one base HTML Element
*/
renderOption(option:IOption):string;
}
