View Binding can bind to a Html element attribute. 

For example, in our blog case, if we want to add a tooltip on the ‘Read More’ button to show the blog title when the user mouse over it as the following screenshot.


 Select the element which you want to set the attribute then click the Attribute button.

On the popup window,

Enter the attribute name on the left field,  such as title, href, class, src and so on, in this case, we will use title.

The right field is the attribute value, bind it to a dynamic field within {} or a static value. The available binding fields may appear as  a clickable button under the field.  In this case, we click {blog_list_Item.Title} button.
