How to inject select2 in angular-json-editor 

We tried to include this plugin

  plugins: {
            select2: {
                enable: true,
                create: false,
                script: 'js/lib/select2.min.js'
            }
        }

but not working. 

Is it done in this way or need to add extra plugin. Please help to include select2 in angular-jason-editor
