i need the result like below image when visible(false) for btn1,btn2
i use scene builder. thanks
In addition to making the components invisible by setting the visible property to false ('visible="false"'), you have set the managed property to false (managed="false").But with explicit 'ColumnConstraints' in your fxml, 'managed=false' will not have effect. So you may want to avoid using ColumnConstraints and instead use GridPane child component's properties to set dimensions.

In scene builder preview button is on exact spot i.e bottom right corner without any gap but when i run my application there is gap.
Button is on a pane and pane is placed on top of anchor pane.
How can i fix this issue?
same thing happening with other components when i placed them on far right or far bottom.
Please examin the sample. Pay attention to min_width, min_height, pref_width, pref_height, max_width, max_height, vgrow, hgrow attributues in SceneBuiler.
The main concept is that type of pane you use sholud give you desired layout. It should not be hardcoded.

Have you put constraints in the layout section of the button? It could be related to that. Check layout x and layout of the button and the pref size x and y of AnchorPane, if that is same, the button must be on the left-bottom corner of the pane.
I have GridPane in my JavaFX window and I span two columns.
When I click on grid lines visible in scenebuilder there is line in the middle of merged cells.
How can I remove or not show this line?
Here is one approach: In this approach, I make the GridPane's background black. Then I stretch each Node to fill their Cell and make the Node's background white. Also on the GridPane, I set all the Insets to 5 and the VGap and HGap to 5. I suggest you use CSS and take #James_D's approach here.

But I would suggest you use CSS and follow #James_D's approach here.
I'm having this weird behavior when I run my JavaFx app:
As you can see the elements aren't properly aligned. I've created that view using SceneBuilder and there isn't that gap in the editor.
My view is composed of a GridPane. The right cells (on the pic) of the GridPane each contains an HBox, each containing elements (buttons / text fields). I haven't configured anything specific here and am not using any CSS.

Am I missing something ?
The default alignment for controls in GridPane (Maybe for controls in general?) is CENTER_LEFT, while for HBox the default is TOP_LEFT. Adding
alignment="CENTER_LEFT"
to your HBox should align them properly.
This question is similar to FXML - Text Field Moves To The Right Upon Button Click but it doesn´t help my case.

Now the interesting part that I don´t understand. Click all but the first (#button1) button and the whole layout moves upward a couple of pixels, it happens once, then the layout has "settled".
A workaround I found, is to force a layout pass after I have added the contents with the buttons.
borderPane.setCenter(node);
borderPane.layout();
Obviously I don´t like the above solution, instead I want to understand why the layout has not settled correctly in the first place.

But if you work with FXML you should use the Scene Builder, which is a WYSIWYG editor.
