ComboBoxInput

require(["esri/form/elements/inputs/ComboBoxInput"], function(ComboBoxInput) { /* code goes here */ });
Class: esri/form/elements/inputs/ComboBoxInput
Inheritance: ComboBoxInput Accessor
Since: ArcGIS API for JavaScript 4.19

The ComboBoxInput class defines the desired user interface for a combo box group.

Coded-value domains are required when using this input type. Previously, fields containing values that weren't compatible with their associated coded-value domain(s) displayed the option and would remove it once a user updated the value. The CodedBoxInput will now display and keep the value but will disable it.
