Ajax-Driven JavaScript ComboBox with Autocomplete
dhtmlxCombo is a cross-browser JavaScript combobox with an autocomplete feature. It extends basic select box functionality and provides the ability to display suggestions while a user types in the text field. dhtmlxCombo can be converted from existing instances of HTML Select, or populated with JavaScript. With Ajax data loading, it can get the list of values dynamically from the server datasource.

(start typing to load country names from server)
dhtmlxCombo can be used in four modes:
- Editable select box - A user can either select a value from the list or type a custom value.
- Read-only select box - A user can select just one value from the associated list of choices.
- Filter - The whole list is loaded on the client side, and as a user begins to type, the list is updated with the appropriate values (which contain or begin from the characters typed).
- Autocomplete - The list is loaded and shown as a user types in the input box.
Like other DHTMLX components, dhtmlxCombo provides a complete JavaScript API to give developers a wide range of options to control the component state and behavior. To manage client-server data communication for dhtmlxCombo, we're offering a dhtmlxConnector extension that simplifies server-side integration (PHP, .NET, Java, ColdFusion).
Since version 4.0, dhtmlxCombo has been overwritten to provide faster loading, better performance, and more customization options. It now supports easy creation of linked combo boxes, sorting, custom text templates, and multiline items.
