Allow to query the DOM with static methods.

[bitplanets]

Sometimes I don't want to create a Widget instance and I have only one class.

[samccone]

Can you provide an example with what you are looking to be able to do?

[bitplanets]

        this.Widget.findAll({
          selector: "." + value
        }).then(function(value){
        })

I want to count the number of items with that class.

[bitplanets]

For example

this.Widget.find({
  selector: "." + value
}).then(function(items){
    console.log(items);
    // console.log(items.length);
})

This works but I get this error

[samccone]

yep makes sense, currently everything is scoped to a widget operation

[bitplanets]

Also remember to make the error more descriptive, in this case you wouldn't even know where to start. Also why this error?

[samccone]

@bitplanets open to PR's to improve the error messages

The error message is because there is no el on the static widget
