I am trying to add a multi-select menu to my HDA, similar to the Group Name parameter of the Group node.
But I found that the Group node's menu is prompted with a checkmark, how do I implement this?

Group node:

Hi,

Thanks for your reply, that's the method I'm using, but I want the selected item to have a tick mark to indicate it is selected like the Group node, is there any way to do that?

You could use an import block to bring in the Group node and then set what you don't want to Invisible. https://www.sidefx.com/forum/topic/76409 [www.sidefx.com]

From what I know the checkmark only shows for single selection options, not the multi selection ones. So try using Replace ( Field + Single Selection Menu) option.

Thank you for your answer, but instead of referencing the Group node's parameter in my HDA panel, I want to create a String parameter and have a similar menu with the "√" symbol.

I tried it, and neither seemed to have the same effect.

When building the menu script, put a checkmark character at the end of the label for the item if it's the current value of the parameter.

Awesome, thanks. I am dynamically building the menu through Python, I guess I would have to query the parameter, find which one is selected, then add the checkmark to the label, is that correct?
Do you happen to have any code for this?

That's what I was thinking.

Sorry, just a random thought, not tested.

Checkmarks seem to be available on menus built with HDK only (I only see them on compiled nodes), I couldn't find a way to do this when building an HDA, in many cases the trick is to promote a parameter that already has that menu with checkmark (group parameter in most cases).

As said by @jsmack, a checkmark string can help here, I tried this and it works fine :

a = ("a", "A")
b = ("b", "B")

pairs = [a, b]

menu = []
for p in pairs:
    menu.append(p[0])
    if p[0] in hou.evalParm("my_list").split(" "):
        menu.append(p[1] + " ✓")
    else:
        menu.append(p[1])

return menu
