Is it possible to have a dynamic context submenu menu on the collection menu?

[retorquere]

I have a submenu that wants to display a variable set of menitems, dependent on the collection that was right-clicked. Is that possible?

[windingwind]

Yes. There is a isHidden property on the argument when creating a menu and by returning a boolean the column is displayed accordingly. Like this:

ztoolkit.Menu.register("collection", {
  "tag": "menu",
  "children": [
    {
      "tag": "menuitem",
      "isHidden": (elem, ev) => {
        return false;
      }
    }
  ]
})

What are elem and ev?

[windingwind]

It's:

zotero-plugin-toolkit/src/managers/menu.ts

Lines 235 to 239 in 2aa66e3

	/**
	* Dynamically hide/show the menu item
	* @returns Whether the menu item should be hidden
	*/
	isHidden?: (elem: XUL.MenuItem, ev: Event) => boolean | undefined;

It's called in the event popupshowing of its parent popup, and that's where the ev comes from

Yes. There is a isHidden property on the argument when creating a menu and by returning a boolean the column is displayed accordingly. Like this:

ztoolkit.Menu.register("collection", {
  "tag": "menu",
  "children": [
    {
      "tag": "menuitem",
      "isHidden": (elem, ev) => {
        return false;
      }
    }
  ]
})

That will allow a set number of menu items to be shown or hidden I think, but I don't know in advance how many there will be, it's dynamic.

[retorquere]

Oh and the label would be dynamic too.

[windingwind]

Yes, you can always set the attributes on the elem

[retorquere]

But a fixed number of items then, correct?

How do I get the selected collection inside isHidden?
