Nested Category Browser Contentful UI Extension

This extension lets you display a nested tree of categories with checkboxes to display and edit which categories are selected.

Requirements

1. A category content type with a bare minimum of a name short text/symbol field and a subcategories multi-reference field; you certainly can have any other fields you want.
2. One category entry with the name Root which serves as the entry point into your category tree. You probably also want to make other categories which will be the actual categories shown.
3. One or more other content types with a multi-reference field called categories (that name is not strictly necessary, but makes the most sense to me :-P ).
4. The contentful-cli tool. If you don't have it, install it by running yarn global add contentful-cli or npm -g install contentful-cli. After installation run contentful login to authorize the contentful-cli tool to use your Contentful account.

Instructions for use

1. Open your terminal, clone this repo (git clone https://github.com/cachrisman/nested-category-browser), and change into the directory created (cd nested-category-browser)
2. Fill in the space ID and delivery token of the space you are using on lines 31 and 32 of nested-category-browser.html.
3. run contentful extension create --space-id SPACE_ID replacing SPACE_ID with the ID of the space in which you want to install this extension
4. In the Contentful webapp, edit your content model and change the appearance of a categories multi-reference field to the Nested Category Browser Extension which you have just uploaded.
