Description:

Use EnsureNavFields to Ensure the list of Fields that the HtmlDropdown command uses exist in the Query. Typically, you would have setup the Query to contain all of the information you wish to use to build a menu with ahead of time, then call EnsureNavFields, and then Set or Build your data into each of the Nav Fields. At the moment, the fields are:

* **Nav.Header** *- An optional Header Group with each item in the Group having the same value, or a single - on just one item to insert a divider with no text based header*
* **Nav.URL** *- URL the Nav Item will link to*
* **Nav.Active** *- True/False flag to auto-add the 'active' class to the item*
* **Nav.Class** *- Optional class(es) to use for this
