Managed Metadata
The Managed Metadata field is a special kind of field that enables site users to select terms from a specific term set. A Managed Metadata column can map to an existing term set, or you can create a local term set specifically for the column.
More about it, in Create a Managed Metadata column article.

JavaScript framework
In this section, you can find basic examples of how to work with the SharePoint fields using JavaScript.
For more examples, check out Working with form fields in JavaScript article. If you are not familiar with the JavaScript framework, get started with the JavaScript basics.
Note
The field is only accessible once the form is rendered, so all calls to the field must be inside fd.spRendered event:
fd.spRendered(function(){
//make field required
fd.field('Field1').required = true;
});
Wait until field is ready
Wait until the field is loaded. The ready method returns a promise that is resolved when the field has been fully initialized and is ready to work with.
fd.field('Field1').ready(function(field) { // alert selected option as a text string alert(field.value.value.name); }); //or fd.field('Field1').ready().then(function(field) { // alert selected option as a text string alert(field.value.value.name); });
Get or set field value
Access and change field value with the following property:
// returns an object
fd.field('TaxonomySingle').value;
// returns the name of the selected option
fd.field('TaxonomySingle').value.name;
// returns the ID of the selected option
fd.field('TaxonomySingle').value.id;
//set element with the an object:
fd.field('TaxonomySingle').value = {
id: "ac68fff3-2826-48f1-8d24-3fadad9533f0",
name: "Test1"
};
// returns an array of objects
fd.field('TaxonomyMulti').value;
// returns the name of the first selected option
fd.field('TaxonomyMulti').value[0].name;
// returns the ID of the first selected option
fd.field('TaxonomyMulti').value[0].id;
//returns all selected options as a text string
var terms = fd.field('TaxonomyMulti').value;
var s = '';
for (var i = 0; i < terms.length; i++) {
s += terms[i].name + '; ';
}
alert(s);
//set element with the an array:
fd.field('TaxonomyMulti').value = [{
id: "ac68fff3-2826-48f1-8d24-3fadad9533f0",
name: "Term1"
},
{
id: "53e1c22e-bfc4-4172-81ff-806415606837",
name: "Term2"
}];
Get the display value
Returns the formatted value of a field when it is displayed on the Display form or is in read-only mode.
//returns selected choice as a string
fd.field('Field1').displayValue;
Handle change event
Execute a function when a field value has been changed:
fd.field('Field1').$on('change', function(value) { //log new value to browser's console console.log(value); });
Make field required
Make a field required or optional:
//make field required fd.field('Field1').required = true; //make field not required fd.field('Field1').required = false;
Disable field
Make a field non-editable. The field value can still be changed with JavaScript and saved:
//disabled field fd.field('Field1').disabled = true; //enable field fd.field('Field1').disabled = false;
Get HTML element
Access HTML element inside the field in order to modify it, hide it, or do something else.
//access field's control var htmlField = fd.field('Field1').$el; //access field's block, which includes title and control var htmlFullField = fd.field('Field1').$parent.$el;
Hide field
Hide a field from a user. The field value can still be accessed and changed with JavaScript.
//hide field fd.field('Field1').hidden = true; //show field fd.field('Field1').hidden = false;
