Visual Input Properties

All visual nodes feature a plethora of visual properties that can be accessed both in the Property Panel and through inputs. These are documented below. Plese refer to the individual node documentation pages to see which nodes feature what visual properties.

Margin

Margins are the spacings around the node, outside of the borders. The margins for the node can be set individually in the Spacing Gadget.

DataDescription
Margin LeftThe left margin in px, or % of the parents width.
Margin RightThe right margin in px, or % of the parents width.
Margin TopThe top margin in px or, % of the parents width.
Margin BottomThe bottom margin in px, or % of the parents width.

Padding

Paddings are the spacings around the nodes content, inside of the borders. The margins for the node can be set individually in the Spacing Gadget.

DataDescription
Padding LeftThe left padding in px, or % of the parents width.
Padding RightThe right padding in px, or % of the parents width.
Padding TopThe top padding in px or, % of the parents width.
Padding BottomThe bottom padding in px, or % of the parents width.

Alignment

To specify how the node is aligned to its parent you can use the Alignment Gadget.

From left to right, the alignment options are:

DataDescription
Align BottomAlign this node to the bottom of its parent.
Align Vertical CenterAlign this node to the bottom of its parent.
Align TopAlign this node to the top of its parent.
Align LeftAlign this node to the left side of its parent.
Align Horizontal CenterAlign this node to the horizontal center of its parent.
Align RightAlign this node to the right of its parent.

Connection Values

When making a connection to the layout property, the values are a little different than the ones in the dropdown. Here is a list of the values, that should be passed in:

Display NameValue
Align Bottombottom
Align Vertical Centercenter
Align Toptop
Align Leftleft
Align Horizontal Centercenter
Align Rightright

Dimensions

Controling the width and height of the node is done with the Dimension Gadget.

The first four controls the Size Mode of the node. It decides how the width and height of the node is specified. From left to right, the options are:

DataDescription
Explicit width and heightSet the width and height directly in pixels or percentage. Percentage is in relation to the parent, so 100% is the same size as the parent.
Explicit height, Content WidthThe node will calculate the width to fit all of its children. The height is explicitly set.
Explicit width, Content HeightThe node will calculate the height to fit all of its children. The width is explicitly set.
Content SizeBoth the width and the height is calculated to fit all of the node's children.

The other properties are:

DataDescription
WidthSpecify the width of this node in pixels, percentage of parent's width or the unit vw which is percentage of the browser window width.
HeightSpecify the height of this node in pixels, percentage of parent's height or the unit vw which is percentage of the browser window height.
FixedControls if an element will try to resize and share space with siblings without going outside of the bounds of the parent.

If Fixed is enabled, the element will be the exact specified size. If it is disabled, the element will resize to fill up empty space, or shrink to make space for siblings.

You can use the Dimension Contstraints Gadget to set a min and/or a max size for the node.

Layout

The supported properties of the Layout Gadget can be very different depending on the node. All possible properties are listed below.

• Position

Controls the layout of this node is in its parent group.

OptionDescription
In LayoutThis node is part of the parent group layout, it will be stacked with its siblings depending on the parent group layout settings.
AbsoluteThis node will not be part of the parent group layout, instead you are free to use the Pos X and Pos Y to place this node explicitly.
StickyBehaves like In Layout, except when the node is about the be scrolled outside the parent. It'll stick to an edge of the parent instead of scrolling away. The edge it sticks to can be controlled with the Alignment input.

• Layout Direction

By default all children are stacked. This property specifies the stacking direction.

DataDescription
VerticalChildren are stacked vertically.
HorizontalChildren are stacked horizontally.
NoneChildren are not stacked.

When making a connection to the layout property, the values are a little different than the ones in the dropdown. Here is a list of the values, that should be passed in:

Display NameValue
Verticalcolumn
Horizontalrow
Nonenone

• Multi Line Wrap

This property specifies what happens with children that are stacked outside of the border of the node.

DataDescription
OffChildren are stacked beyond the boundaries of the node. If Clip is enabled they will not be visible.
OnChildren are wrapped to the next row or column (depending on layout direction).
On ReverseSame as On but opposite layout direction.

• Gap

This property is used to add spacing between children in the group.

DataDescription
Vertical GapVertical space between children. Shown if Layout is set to Vertical or Multi Line Wrap is On.
Horizontal GapHorizontal space between children. Shown if Layout is set to Horizontal or Multi Line Wrap is On.

• Clip content

This property controls if elements that are too big to fit inside the node will be clipped.

If disabled, a group will always expand to contain all of its children. So if the children are taller than the size of the group, the group will expand and be larger than its specified size.

Align and justify content

This Gadget controls how children are aligned and justified by default. Children can override these settings with their Alignment input.

The first set of options control cross-axis alignment, meaning vertical alignment for horizontal layouts, and horizontal alignment for vertical layouts. From left to right, the options are:

OptionDescription
Align items startChildren are stacked at the start of the parent.
Align items centerChildren are stacked at the center of the parent.
Align items endChildren are stacked at the end of the parent.

The second set of options control alignment in the same direction as the layout. From left to right, the options are:

OptionDescription
Justify content startChildren are stacked at the start of the parent.
Justify content centerChildren are stacked at the center of the parent.
Justify content endChildren are stacked at the end of the parent.
Justify content space betweenChildren are evenly distributed. No space is added between the parent and the first and last child.
Justify content space aroundChildren are evenly distributed. Space is added between the parent and the first and last child.
Justify content space evenlyChildren are evenly distributed with equal space between them.

Scroll

This Gadget controls how scrolling should be handled within the node.

DataDescription

Placement

The Placement Gadget lets you offset, rotate and scale the node. It uses CSS Transforms under the hood, meaning that the nod will still take up the original size and position in the visual tree.

DataDescription
Pos XThe X position of the node. Either relative to its parent top left corner or relative to its layout position depending on the Position property. Can be specified in pixels or as a percentage of its parent's width.
Pos YThe Y position of the node either relative to its parent's top left corner or relative to its layout position depending on the Position property. Can be specified in pixels or as a percentage of its parent's height.
RotationThe rotation in degrees.
ScaleSpecifies scaling of this node. A value of 0 scales the node down completely so that it is no longer be visible. A value of 1 gives it the original size, and a value of 2 doubles the size and so on.
Transform Origin XSpecifies the X position, within this node, that will be the center for rotation and scale. By default it is the center of the node (i.e. 50%) but you can specify an arbitrary value in either percentage of the node's width or explicitly in pixels.
Transform Origin YSpecifies the Y position, within this node, that will be the center for rotation and scale. By default it is the center of the node (i.e. 50%) but you can specify an arbitrary value in either percentage of the node's height or explicitly in pixels.
