Hi All,

I want to implement auto suggestion feature in textbox. Is there any plugin or extensions are available in extjs 4?

If somebody has implemented, please share the code.

Auto-suggest style functionality is actually available through the ComboBox class. You can turn the trigger off if you want to make it look more like a combobox.

The forum search example shows this functionality mixed with a custom template for the display though a more traditional google suggest look and feel will be the default if you just set it up with a remote data store and turn off the trigger.
