AutoComplete Control: Combobox, with CSS for Multiple Stacked Instances
This "combo box" AutoComplete implementation allows the user to pick an item from a set list or enter a custom value directly into the input field. Please note the following custom CSS:
- z-index has been applied to support multiple vertically stacked AutoComplete instances
- the input field and container have been styled to support a button inline to the right
Implementers who are working with data from third-party sources, user input data, or otherwise untrustworthy sources should be sure to read the Security Considerations section of the AutoComplete user guide.
