objective
=========

I have a div that I want to make act like a tooltip with reactjs.

HTML
----

```
<div>on hover here we will show the tooltip</div>
<div>
    <div class="tooltip_custom">this is the tooltip!!</div>
</div>

```

I am used to angularjs using the `ng-show` with a condition on the `<div>` , I was wondering if there is such binding in reactjs , or else how can I do this functionality ?

Thanks
