Search and Editing
Set the searchEnabled property to true to allow users to search. The following properties 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 SelectBox should display the unfiltered item list until a user have typed in the minimum number of characters (minSearchLength).
Set the acceptCustomValue property to true to allow users to add values to the SelectBox. You should also implement the onCustomItemCreating handler to create new data source entries.
Feel free to share demo-related thoughts here.
