ngTagsInput css issue

I'm using ngTagsInput plugin to render some autocomplete tags. I have used this in one of my previous projects and worked fine.

However , in my new project , when I add the ngTagsInput css, it doesnot show the text area for user to type tags. I checked the css and couldn't find anything overrides the ngTagsInput css.

please have a look at the plnkr I've created to demonstrate the issue. It shows only the button, but not the tags-input directive.

how can I fix this css.

Thanks in advance

cheers

You have forgotten to include the JS file and add the module dependency.

index.html

<script src="https://cdnjs.cloudflare.com/ajax/libs/ng-tags-input/2.3.0/ng-tags-input.min.js"></script>

app.js

angular.module('starter', ['ionic', 'starter.controllers', 'ngTagsInput'])

See next plnkr
