UI hint for collapsing booleans

jelte_steur814

In the native Extrude feature, there are these boolean annotations with a blank 'group' arrow in front of it. when the boolean is selected, the 'group' expands.

What UIHint can I use to get that same behaviour? when I group parameters, there is always a group name taking up a line and when collapsed, hiding the first boolean.

It's not a UIHint. It's a "driving parameter" field. Look here for the info. https://cad.onshape.com/FsDoc/uispec.html

annotation { "Name" : "Additional Options" }
definition.additionalOptions is boolean;

if (definition.additionalOptions)
{
    annotation { "Group Name" : "Options", "Collapsed By Default" : false, "Driving Parameter" : "additionalOptions" }
    {
        annotation { "Name" : "Option" }
        definition.option is string;
    }
}
