Sorry, we can't retrieve the data from server. Please comeback later.

If you want to customize a drop-down menu item, follow the steps below:

  1. Implement a component that renders item markup.
    The item is an IAction object. You can use component props to access it.

  2. Register the component so that it can be accessed by name.
    In React, register the component in ReactElementFactory as shown in the JavaScript tab.

    In Vue and Knockout, use techniques native to these libraries:

  3. Assign the component name to the Dropdown question's itemComponent property in the survey JSON definition.
