  • don't use this component nested a HTML tag block with *ngIf directive if you is using an Angular last than 8 version, or it'll not work;
  • enablePageNumberInputBox is optional, if you set it, you'll can browse to a specific page, just clicking on the page number box to enable the page number input box (text input type) and clicking in previous page button (if the page number is smaller than current) or next page button (if the page number is bigger than current). If you enable the page number input box you can set widthGrowthToggleFactor to define the width growth factor of the page number input box;
  • You can use the getPagePer pipe passing the page number and the limit to page a collection (... | getPagePer:pageNumberVariable:limitVariable) inline.
