I would approach this problem using Session. You could target the data using a click event:
Template.vehicles.events({
'click .vehicle-nav li': function(){
Session.set('selected-vehicle', this._id); // or however you id the docs in your app.
}
});
then create an event helper that gets the selected doc and returns it to the template.
Template.vehicles.helpers({
getSelectedVehicle: function() {
var selectedId = Session.get('selected-vehicle');
return cars.findOne(selectedId);
},
});
Session is a great and simple tool to manage user state, like what vehicle they have selected.
Finally, you would then need to get the values in your template somewhere
<!-- html-->
{{#if getSelectedVehicle}}
{{#with getSelectedVehicle}}
<!-- mark up, when using with you can access doc atts directly. -->
{{/with}}
{{else}}
<!-- tell the user to make a selection -->
{{/if}}
using with in this context can lead to more readable markup. But there are other ways to achieve the same result.
To recap, at a high level, You are targeting the users interactions with the UI, to set a global variable as a way to simplify managing state. Be sure to check out Session in the meteor docs, its very simple and powerful. (the above code is not tested, but hopefully conveys the idea)
