Mega Menu

About 1 mincomponentsviews

The Mega Menu builds a horizontal menu bar with large multi-column dropdown panels, driven by an asset hierarchy. Top-level assets become the menu headers; their children fill the dropdown sections. Each item links to a view or URL taken from the asset's attributes — so the whole navigation menu is generated from your asset model.

Experimental component

Mega Menu is currently experimental — its settings and behavior may change.

Quick Start

Drag the Mega Menu onto the canvas and bind an element-search channel pointing at the root of the hierarchy you want as the menu. Top-level nodes become the menu headers; opening one lazy-loads its child sections. To make items navigate, add url (and optionally target) attributes to the assets — the menu reads those to build each item's link.

Generic Settings

Each IOTA component shares a set of generic settings. Expand each section below:

Workspace

These settings are applicable to the whole view.

Grid Properties

The grid is provided for convenience when developing dashboards as visual guides and snapping capability.

By default the work area grid is enabled and can be customized or even disabled in this menu.

Property Name	Description
Grid Color	Color of the grid
Grid Size	Size of the grid step
Snap to Grid	Enable/Disable snapping to the grid
Show Grid Lines	Show the grid as lines
Show Grid Dots	Show the grid as dots

Align Controls

The Align controls provides a means to align and distribute selected objects on the display.

Align Objects

You can align several components horizontally using the Align-left, Align-center or Align-right controls
You can align several components vertically using the Align-top, Align-vertical-center or Align-bottom controls

Distribute Objects

You can distribute several components on the vertical/horizontal axis by selecting them (select at least 3 components) and pressing Align-vertical/Align-horizontal
You can make all the selected components the same width/height by selecting them and pressing Adjust Width/Adjust Height

Tips

Hold the Ctrl button to select several components. The oldest component is used as a reference.

Anchor Points Options

The anchor points are eight squares around an object that allow you to resize the object. The anchor point options allow you to define the appearance of the anchor points.

Property Name	Description
Reference Point Color	Sets the color of the reference point (see Rotation and Position for more details)
Anchor Points Color	Sets the color of the rest of the seven anchor points
Point Options Color	Sets the color of the point options (only for Line and Bezier Curve)
Show Point Options	Show/Hide the point options

Locked View Options

These options define the appearance of the component border in the locked view for the selected component.

Property Name	Description
Active Border Fill	Sets the fill color of the border
Active Border Width	Sets the width of the border

Variable

Every component has a unique variable name. This variable name can be used to reference the component in multi-state configurations and other scripts.
On creation, every component is given a default name. This can be overwritten to be more user-friendly. To do so simply overwrite the value in the variable input field.

Arrange / Remove

Send Backward - move object one layer down
Bring Forward - move object one layer up
Send to Back - place object under all layers
Bring to Front - place object above all layers
To send/bring objects to the front/back use the first four buttons.
Any set of components can be deleted by either using the button or delete/del keyboard keys.

Rotation and Position

Reference Anchor Point - allows you to select one of the anchor points as a reference so that you can set an Angle (clockwise) of incline relative to this point.
By default the reference anchor point is the top left corner. You can also rotate the component by dragging one of the yellow corner points.
You can set the position of the component by setting the X and Y coordinates relative to theReference Anchor Point and the top-left corner of the work area.
You can drag any of the anchor points to change the width and height of the component, or you can set it manually by editing the Width and Height boxes.
Set Lock Aspect Ratio so that while changing width and height, the component width to height ratio stays the same
Transform allows you to view the component as a mirror or a reflection of itself

Actions

Actions or multi-states are programmable conditional states handled by user-generated code.

Note

Actions that have script handlers are marked with a circle

in the top right corner.

The currently supported actions are described in the table below:

Action	Trigger
OnCreate	When the component is created
OnFocus	When the component is selected
onClick	When the component is clicked or the selection is changed
onData	Each time the data changes for assigned channels
onTick	20 times per second
onDblClick	On mouse double click
onHover	When the mouse is over the component (and not when the mouse is not)

Properties

The properties menu for Channels allows you:

to modify the Label of the DataSource
to set UOM, lower and upper values
to choose number format and displayed digits
to adjust the line formatting for trend line components
to configure the additional regression lines that can be plotted for supported components

Component Specific

Load Attributes — load each node's attributes (needed for URL-based navigation). Default on.
Use Attribute URL Values — build item links from attributes rather than #. Default on.
URL Attribute Name — the attribute holding each item's link (default url).
Target Attribute Name — the attribute holding the link target (default target).
Template Filter — restrict items to a specific asset template.
URL Query Param — a query parameter for deep-linking a selection.

Sections Per Row — 1–6 columns of sections in each dropdown panel (default 4).
Menu Items Layout — List or Grid.
Show Full Name, Show Description.

Visual Properties & Font

Menu, active-menu, section-header, and item colors (fill, text, hover), plus border and shadow; separate fonts for the title, menu, section headers, and items.
