Use a Menu () node to customize a context menu or toolbar of the physics interface. This node adds a submenu.

To add a Menu node, right-click the Physics Interface or Multiphysics Interface nodes and add it from the context menu. You can also right-click a User Input or Selectable Input node and select it from the Buttons menu.

Right-click the Menu node to add Item and Item / Button, Toggle Item, Separator, or Item Link nodes or another Menu node, which acts as a submenu. You can also add an Activation Condition.

The Settings window includes the following sections:

In this section, add parameters to the table with a Name, Description, and Default expression. With the parameters, you can parameterize the link that linked to this node. For example, the Item Link can link to a Menu node, but they can use different titles and icons. Select the Ready only check box to prevent editing of the expression in the Item Link node.

In the Settings window for Menu, enter a Title of the menu in the text field and an icon file in the Icon field (or click Browse () to pick an icon file from the file system). You can also click the downward arrow beside the Browse button and choose Browse From () to open the fullscreen Select File window. Click the downward arrow for the File Location Actions menu () to choose Show in Auxiliary Data () to move to the row for this file in the Auxiliary Data window, Copy File Location (), and (if you have copied a file location) Paste File Location ().
