external taglist for multiselect? about react-widgets

[jquense]

I'm not quite sure what you mean by externally. Could you expand or maybe illustrate what you have in mind? which is to say, i might very well be open to it once i understand it!

Sure.. styles a bit out of whack, but here's a quick example:

Basically what i'd like to be able to do is set a container for the taglist that isn't the multiselect itself.

gotcha. I have actually had this need also. I think it would be tough to structure a PR that would work well in this case, and I don't think that this sort of thing makes a lot of sense in the library proper. But I do want to make sure the widgets are flexible and extensible enough that stuff like this is easy enough to do yourself. In this case I think we are already there, provided you feel comfortable using a technically private component.

This is a bit of an oversimplification, you may have to cover some edge cases (like figure out how you'd want keyboard navigation of tags to work here), but you can easily wrap this pattern up into a few components in your own code to reduce some of the wiring needed to get it working.

var Multiselect = require('react-widgets/lib/Multiselect');
var TagList = require('react-widgets/lib/MultiselectTagList');

var App = React.createClass({

  getInitialState(){
    return {
      data: list,
      values: [],
    }
  },

  render(){
    var self = this;

    function onChange([value]){
      self.setState({
        values: self.state.values.concat(value), 
         // remove the value from the data list so it can't be re-selected
        data:   self.state.data.filter( v => v !== value)
      })
    }

    function onDelete(val){
      self.setState({
        values: self.state.values.filter( v => v !== val),
        data:   self.state.data.concat(val)
      })
    }

    return (<div>
            <Multiselect data={this.state.data} value={[]} onChange={onChange} />
            <TagList value={this.state.values} onDelete={onDelete} />
      </div>)
  }
})

The above is written in es6 you can look here to see the compiled es5 version

that works perfectly, thanks for the quick response!
