I Want To Remove The Icon In The Red Frame. What Do I Have To Do Have An Example Of An Angular 5 Code?

Hi Attapol,
 
Thank you for posting your question.
 
There are two articles in the documentation that would help you to complete your task.
The first one is about the Toolbar customization. The icons you would like to remove are the tabs of the Toolbar. You will find the details on how to remove them in the following article: https://www.flexmonster.com/doc/customizing-toolbar/.
The second article is about the integration with Angular: https://www.flexmonster.com/doc/integration-with-angular/. It explains how the event handlers can be specified for the pivot table. You need beforetoolbarcreated event to remove the tabs from the Toolbar.
 
Kind regards,
Iryna
