Form

Deprecated

This node is deprecated and kept only so existing projects keep working. It is not offered in the node picker for new use.

Legacy HTML form container with an onSubmit signal, hidden from the picker. Use a Group and wire actions explicitly.

Form renders an HTML form element around its children and fires onSubmit on native submission (e.g. Enter in a field). It is hidden from the node picker; current graphs wire submission explicitly — button onClick / input onEnter into the action — inside a plain Group, keeping the trigger visible in the graph.

When to use it

Do not use in new graphs — use Group with explicit click/enter wiring instead.

Inputs

Values

Name	Type	Default	Description
alignX	Enum (left, center, right)	—	Horizontal alignment of this element within the space its parent gives it
alignY	Enum (top, center, bottom)	—	Vertical alignment of this element within the space its parent gives it
boxSizing	Enum (border-box, content-box)	border-box	Whether Width and Height include this element's padding and border, or only its content
cssClassName	String	``	Extra CSS class names to put on this element, for styling from a stylesheet you supply
flexDirection	Enum (none, column, row)	column	—
height	Dimension	100	Height of the element; how the value is read depends on Size Mode
marginBottom	Number	—	Space outside the element's bottom edge, between it and its neighbours
marginLeft	Number	—	Space outside the element's left edge, between it and its neighbours
marginRight	Number	—	Space outside the element's right edge, between it and its neighbours
marginTop	Number	—	Space outside the element's top edge, between it and its neighbours
maxHeight	Number	—	Largest height the element may grow to, taking priority over Height
maxWidth	Number	—	Largest width the element may grow to, taking priority over Width
minHeight	Number	—	Smallest height the element may shrink to, taking priority over Height
minWidth	Number	—	Smallest width the element may shrink to, taking priority over Width
mixBlendMode	Enum (normal, multiply, screen, overlay, darken, lighten, color-dodge, color-burn, hard-light, soft-light, difference, exclusion, hue, saturation, color, luminosity)	normal	How this element's colours blend with whatever is painted behind it
mounted	Boolean	true	Removes the element from the page entirely when false, unlike Visible which leaves its space behind
opacity	Number	1	How opaque this element is, from 0 for invisible to 1 for solid
paddingBottom	Number	0	Space inside the element's bottom edge, between it and its content
paddingLeft	Number	0	Space inside the element's left edge, between it and its content
paddingRight	Number	0	Space inside the element's right edge, between it and its content
paddingTop	Number	0	Space inside the element's top edge, between it and its content
position	Enum (relative, absolute, sticky, fixed)	relative	How the element is placed: In Layout follows its siblings, Absolute ignores them, Sticky pins to the parent edge on overflow, Fixed stays put and takes no space
sizeMode	Enum (explicit, contentWidth, contentHeight, contentSize)	contentSize	Whether Width and Height are used as given, or the element sizes itself to fit its contents
styleCss	String	/* background-color: red; */	Raw CSS declarations applied to this element, overriding the styling ports above
transformOriginX	Number	50	Horizontal point the element rotates and scales around, as a fraction of its width
transformOriginY	Number	50	Vertical point the element rotates and scales around, as a fraction of its height
transformRotation	Number	0	Rotates the element clockwise in degrees, without affecting the layout
transformScale	Number	1	Scales the element about its transform origin; 1 leaves it unscaled
transformX	Number	0	Moves the element right after layout, without moving its siblings
transformY	Number	0	Moves the element down after layout, without moving its siblings
variant	String	—	Name of a saved variant of this node type to apply, replacing the styling set here
visible	Boolean	true	Hides the element while keeping the space it occupies in the layout
width	Dimension	100	Width of the element; how the value is read depends on Size Mode
zIndex	Number	—	Paint order among overlapping siblings; higher numbers paint on top

Outputs

Values

Name	Type	Default	Description
boundingHeight	Number	—	Height this element actually ended up with after layout, in pixels
boundingWidth	Number	—	Width this element actually ended up with after layout, in pixels
childIndex	Number	—	This element's position among its parent's children, counting from 0
childrenCount	Number	—	How many child elements are currently mounted inside this one
screenPositionX	Number	—	Distance in pixels from the left edge of the window to this element's left edge
screenPositionY	Number	—	Distance in pixels from the top edge of the window to this element's top edge
this	Reference	—	A reference to this node itself, for ports that take a node rather than a value

Signals

Name	Type	Default	Description
didMount	Signal	—	Fires once this element has been added to the page and can be measured
onSubmit	Signal	—	—
willUnmount	Signal	—	Fires just before this element is removed from the page, while it still exists

Dynamic ports

This node's port list changes at runtime (declared-port-groups); the tables above may be incomplete for a given instance.

Declares conditional/expandable port groups whose visibility depends on parameter values (see declaredPortGroups).

Condition	Inputs shown	Outputs shown
sizeMode = explicit OR sizeMode = contentHeight	width	—
sizeMode = explicit OR sizeMode = contentWidth	height	—

Ports at runtime

Declared-port-groups: size-mode-dependent layout ports, as on other visual containers.
