The Advanced Datalist Input plugin is used to provide an “autocomplete” feature on input elements. Users will see a drop-down list of pre-defined options as they input data. Unlike HTML5 datalist the Advanced Datalist Input has the following benefits:

• Autocomplete, filter and search works correctly under all browsers including Edge, old and new versions of Safari, Opera, Internet Explorer, etc.
• Allows a user to remove items from the list
• Return the id of the selected item instead of text

The appearance is easy customizable using CSS. See detailed help here.
