How to relocate or resize items using mouse in Intellij Idea scene builder?

Question

I am using Intellij Idea scene builder. I am unable to resize or make relative designs using mouse. Whenever I try to place an item this happens:

I can't resize items using mouse also. Here is the fxml code:

<?xml version="1.0" encoding="UTF-8"?>
<?import javafx.scene.control.Button?>
<?import javafx.scene.layout.AnchorPane?>

<AnchorPane prefHeight="300" prefWidth="500" xmlns="http://javafx.com /javafx/8.0.172-ea" xmlns:fx="http://javafx.com/fxml/1" fx:controller="sample.Controller">

</AnchorPane>

Is there any issue or I am missing some code?
