How to use a static enum in another class in typescript

Using this question and answer as a reference, Can you set a static enum inside of a TypeScript class?, I created an enum and made it a static property in my class as follows

/* Input.ts */
enum INPUT_TYPE { TEXT, RADIO, CHECKBOX }
export class Input {
    static INPUT_TYPE = INPUT_TYPE;
    readonly inputType: INPUT_TYPE;

    constructor (inputType: INPUT_TYPE) {
        this.inputType = inputType;
    }
}

Yes, this is a basic class, used as an example.

I have a second class in another file that needs to use it.

import {Input} from "./Input";
/* InputLabel.ts */
export class InputLabel extends Input {
    readonly label: string;

    constructor(label:string, inputType: Input.INPUT_TYPE) {
        super(inputType);
        this.label = label;
    }
}

I'm using IntelliJ IDEA and have the "Language & Frameworks" -> TypeScript: "TypeScript version:" custom pointing to my current version, which is 2.0.2. IntelliJ is complaining to me and stating that it cannot find the namespace 'Input'.

If you want it to work this way, just write

/* Input.ts */
export class Input {
    readonly inputType: Input.INPUT_TYPE;

    constructor (inputType: Input.INPUT_TYPE) {
        this.inputType = inputType;
    }
}
export namespace Input {
    export enum INPUT_TYPE { TEXT, RADIO, CHECKBOX }
}
