# Resizable Split Pane Layout
This has been adapted from the [@11mb/angular-resizable](https://github.com/11mb/angular-resizable), itself an Angular2 version of  [@reklino/angular-resizable](https://github.com/Reklino/angular-resizable) for AngularJS. Similar work in JavaScript: [@RickStrahl/jquery-resizable](https://github.com/RickStrahl/jquery-resizable); [Split.js](https://split.js.org/) by [@nathancahill](https://github.com/nathancahill/split/).

## Usage
Installation instructions
Install ngx-bootstrap from npm:

```
npm install @3dgenomes/ngx-resizable --save

        |        >        |    Cells: dragbar on right '>'
        + v v v v v v v v + 
        |        >        |
  Row 2 | Cell 3 > Cell 4 |
        |        >        |
        +--------+--------+
```
```
<div class="content">
  <rsz-layout class="row" [directions]="['bottom']" [rFlex]="true">
    <rsz-layout class="cell" [directions]="['right']" [rFlex]="true">
      <p>Cell Content 1</p>
    </rsz-layout>
    <rsz-layout class="cell" [directions]="['none']" [rFlex]="false">

    </rsz-layout>
  </rsz-layout>
  <rsz-layout class="row" [directions]="['none']" [rFlex]="false">
    <rsz-layout class="cell" [directions]="['right']" [rFlex]="true">
      <p>Cell Content 3</p>
    </rsz-layout>
    <rsz-layout class="cell" [directions]="['none']" [rFlex]="false">
