Select Box

Search and Editing

Set the searchEnabled option to true to allow users to search. The following options help you configure the feature:

  • searchExpr
    Specifies one or several data fields to search.
  • searchMode
    Specifies whether found items should contain the typed-in string or start with it.
  • searchTimeout
    Specifies the delay between the moment a user stops typing and the moment the search is executed.
  • minSearchLength
    Specifies the minimum number of characters that a user should type in to trigger the search.
  • showDataBeforeSearch
    Specifies whether the widget should display the unfiltered item list until a user have typed in the minimum number of characters (minSearchLength).

Set the acceptCustomValue option to true to allow users to add values to the SelectBox. You should also implement the onCustomItemCreating handler to create new data source entries.
