Hello,
You do not have a filter added to your data source as it it explained in the video.

hello Teodor
but...I am very sure that I really have a filter
www.littlebau.com/key.gif

I do not see any filter applied to the datasource on the link you provided..

/* dmxDataSet name "qa_html5_datasource" */
       jQuery.dmxDataSet(
         {"id": "qa_html5_datasource", "url": "dmxDatabaseSources/qa_html5.php?sort=nowtime&dir=desc&limit=3", "dataSourceType": "database", "dataType": "jsonp"}
       );
  /* END dmxDataSet name "qa_html5_datasource" */

hi Teodor
but I really according to the teaching video step by step
well...
could you just tell or help me，how to achieve this function (filiter by my database results instantly as my input field)

Open the query builder and reapply the filter. Make sure to uncheck the Req checkbox.

hi Teodor
work done after I uncheck the Req checkbox
the teaching video said about this...My careless...sorry
